The location of the internal organs of a man. Human anatomy: What we have inside and where organs are located. Pictures of the structure of a person for children

Probably, for any person, knowledge of the structure and location of their internal organs represents not the latest value. Otherwise, as we can determine where and that we have hurts, which is extremely necessary to prevent and treat the widest range of diseases and disorders.

Of course, professional diagnostics must be fully entrusted to the attending physician, but, nevertheless, know the location of the internal organs in humans, the general scheme of location is necessary not only for themselves personally, but also in order to give first aid to their close, for example, to the child ...

So what are the internal organs? The answer is simple: these are such education in the human body that are inside. We do not see them, we cannot actively manage them, but for that, we feel good how they work, if ... they are sick. Surely you have heard that while the heart does not hurt, a person does not know where it is at all. So any other formation inside the body. External authorities All you know: Hands, legs, head, senses and sensations (visual, auditory, olfactory, tactile (tactile), taste).

Among the internal organs, organs of the chest, abdominal and pelvic cavity should be distinguished. We will show their location, scheme and general information about them.

Organs

The human body represents the most complex mechanism consisting of a variety of cells forming live tissues. From the tissues, organs are obtained that are called internal, since the location of the organs in humans is inside.

Many of the organs are known to almost every younger schoolboy. In most cases, so far will not surfacitate, people do not think about what they are inside.

Organ system and apparatus

Under the system of organs understand their group having anatomical and embryology relationship. The system of organs performs a single function in the body.

Under the device understands closely arranged and interrelated organs that do not have kinship.

SPLANTERNOLOGY - What is?

Slantography is the doctrine of the internships, a special section of anatomy engaged in the study of the location of the organs in humans, those structures that are in the body cavities.

The organs of the abdominal cavity of the person participating in the digestion are studied primarily. Their location is the following.

Then there is a study of the urogenital, urinary and sexual system. This section discusses endocrine glands near these systems.

The human brain also refers to the internal organs. In the cranial box is the head, and in the spinal canal - the spinal cord. However, the human brain in detail in this section is not studied.

All organs appear in the form of systems operating with full interaction with the whole organism. There are respiratory, urinary, digestive, endocrine, reproductive, nervous and other systems.

Man's location in humans

Human organs are in several specific cavities: chest, abdominal and pelvic.

So, in the chest cavity, located within the borders of the chest and the upper diaphragm, are three others. It is a pericard with a heart and two pleural on both sides with the lungs.

In the abdominal cavity there are kidneys, stomach, most of the intestines, liver, pancreas and other organs. It is a torso located below the diaphragm. It includes the abdominal itself and the pelvic cavity.

The abdominal is divided into the retroperitoneal space and the cavity of the peritoneum. The pelvic contains the excretory and reproductive system.

To understand even more detailed location of human organs, the photo below serves as a supplement. On one side, the cavities are depicted on one side, and on the other hand, the main bodies that are in them are.

The structure and scheme of human arrangement

1. hollow or tubular (stomach, blade and gallbladder, intestines: thin and thick intestine;
2. parenchimato and dense (pancreas, spleen, liver).

The first in their tubes have several layers, which are also called shells. From the inside the mucous membrane is enjoyed, which plays mainly a protective function. Most organs on it have folds with outgrowths and deepening. But there are completely smooth mucous membranes.

In addition to them, there is a muscular shell with circular and longitudinal layers, separated by a connective tissue.

On the human body there are smooth and transverse muscles. Smooth - prevail in the respiratory tube, urinary organs. In the digestive tube, transverse muscles are located in the upper and lower departments.

In some groups of organs, there is another shell, where vessels and nerves pass.

All components of the digestive system and lungs have a serous shell, which is formed by a connective tissue. It is smooth, thanks to which there is a slight slip of the insides about each other.

Parenchimatous organs, unlike the previous ones, do not have cavities. They contain functional (parenchyma) and connecting (stromas) tissue. Cells performing the main tasks form a parenchyma, and the soft core of the organ is formed with stroma.

Men's and women's organs

With the exception of the genital, the location of human organs - both men and women - is the same.

1. In the female organism, for example, there are vagina, uterus and ovaries.
2. In men's - prostate gland, seed bubbles and so on.

In addition, men's organs are usually larger than women and weigh, respectively, more. Although, of course, it is found and on the contrary, when women have large forms, and men are small.

Sizes and functions

As the arrangement of human organs has its own characteristics and their size. Of the small, there are, for example, adrenal glands, and from large intestines.

As is known from the anatomy and shows the location of man's organs the photo above, the total weight of the internship can be about twenty percent of the entire body weight.

In the presence of diseases, the size and weight of the organs can, how to decrease and increase.

The functions of the organs are different, but they are closely interconnected with each other. They can be compared with musicians playing on their tools under the control of the conductor - the brain. There are no unnecessary musicians in the orchestra. Also, however, and there is not a single unnecessary structure and system in the human body.

For example, due to breathing, digestive and excretory systems, the exchange is implemented between the external environment and the organism. The genitals provide reproduction.

All systems are vital.

Systems and apparatus

Consider the overall features of individual systems.

Skeleton is a musculoskeletal system, which includes all bones, tendons, joints and somatic muscles. It depends on both the proportion of the body and movement and locomotion.

The location of the organs of the human cardiovascular system provides blood movement along the veins and arteries, the saturation of the cell by oxygen and nutrients, on the one hand, and deriving carbon dioxide with other exhaust substances from the body, on the other. The main body here is the heart that constantly pumps blood along the vessels.

The lymphatic system consists of vessels, capillaries, ducts, trunks and nodes. Under a slight pressure of the lymph moves through the tubes, providing the withdrawal of waste of life.

All internal organs of a person, the location scheme of which is shown below, are regulated by means of a nervous system, which consists of central and peripheral departments.

1. The main (central department) includes a spinal and brain.
2. Peripheral consists of nerves, plexuses, roots, gangliy and nerve endings.

The functions of the system are vegetative (responsible for the transfer of pulses) and somatic (connecting the brain with skin and ODE).

The sensory system belongs to the main role for fixing the reaction to external stimuli and changes. It includes nose, language, ears, eyes and leather. Its occurrence is the result of the work of the nervous system.

The endocrine system along with the nervous regulates internal reactions and sensations of the environment. Emotions, mental activity, development, growth, puberty depend on its operations.

The main bodies in it are the thyroid and pancreas, testicles or ovaries, adrenal glands, epiphysis, pituitary gland and thymus.

The reproductive system is responsible for reproduction.

The urinary system is completely in the pelvic cavity. She, like the previous one, differs depending on the floor. The need for the system is to withdraw toxic and alien compounds, an oversupply of various substances through the urine. The urinary system consists of kidneys, urethra, ureterals and bladder.

The digestive system is the internal organs of man in the abdominal cavity. Location scheme Next:

Its function, logical outgoing from the name, is to extract and deliver nutrients into the cells. The arrangement of human abdominal organs gives a general idea of \u200b\u200bthe process of digestion. It consists of mechanical and chemical processing of food, suction, splitting and removal from the body of waste.

The respiratory system consists of the upper (nasopharynx) and lower (larynx, bronchi and trachea) departments.

The immune system is the protection of the organism from tumors and pathogens. It consists of thymus, lymphoid fabric, spleen and lymph nodes.

Skin cover protects the body from temperature drops, drying, damage and penetrate pathogenic microorganisms and toxins. It consists of leather, nails, hair, sebaceous and sweat glands.

Internal organs as a basis of life

The photo presents the location of the internal organs of a person with a description.

It can be said that they are the basis of life. Without the lower or upper limbs, it is difficult to live, but still you can. Similarly, without a spleen. But without a heart or liver, a person cannot live at all.

Thus, there are organs that are vital, and there are those without which life is difficult, however, it is possible.

At the same time, some of the first components have a paired structure, and without one of them, the entire function goes to the remaining part (for example, kidneys).

Some structures are capable of regenerated (this applies to the liver).

Nature endowed the human body with the most complex system to which he should carefully relate and protect what he was given in the allotted period.

There are people neglecting the most elementary things capable of maintaining the body in order. Because of this, he besides the time. Diseases appear, it comes premature old age and a person leaves his life when he has not yet done all the cases that should have.

All human body bodies have an individual structure and location. They perform a vital role in maintaining the normal functioning of the body. It is important to know the location of the main organs to cope with any complications, injuries or unmistakably determine the doctor's profile to which you want to seek help.

The following description of the location of the main internal organs of the human body makes it possible to better understand the structure of its body and determine the authority in which changes began to occur.

The abdominal bodies are what every person has and is invariably, day after day, provides a normal well-coordinated work of the body. Unfortunately, very few know what a scheme is or where are these internal organs, their departments and what are their structure in general?

The location of the abdominal organs

The abdominal bodies include the following systems: kidneys and adrenal glands, bubble and ureter, as well as the liver, spleen and the entire gastrointestinal tract. From the front and on the sides, their location is limited by the abdominal wall, which is permeated with muscles, as well as fatty tissue and connecting and intestinal formations that are present at everyone without exception, which can be seen in all pictures.

In general, the abdominal cavity can be designated as all the space that is under the diaphragm. It is in it that all organs are concentrated, and the abdominal region goes into pelvic. The space for the peritoneum is characterized by the fact that it is eliminated by a serous shell, which extends to all internal human internal organs.

It should be paid to the fact that due to some physiological features, the friction of the surfaces of the internal organs does not occur on each other. Such effect is achieved due to the presence of epithelial cover, as well as serous fluid, complementing the structure, which is visible in the pictures and in the photo. The separator of organs that relate to the chest and abdominal cavity is a diaphragm, the location of which is always the same.

In the upper region of the peritoneum there is a stomach and its departments that enlite themselves. It is known that it is its number directly affects the dimensions of this man. The stomach itself is reminded by a small bag that has a specific output, namely the tube, which is known as the intestines.

It is assigned certain functions, for example, the suction of the main part of the nutrient components.

Presented the presented departments of the gastrointestinal tract from any person with a posterior hole, which is obvious on any photo or pictures. Experts indicate the following features that determine the structure of this system:

1. a spleen belongs to the abdominal cavity and space for peritoneum. This happens, despite the fact that it belongs to the lymphatic system, but it can be detected (for example, during an ultrasound) under the left hypochine;
2. the upper part of the abdominal area occupies a liver, which is attached to the diaphragm, the stomach, as well as the intestines and the abdominal wall by means of ligaments. It is she who is responsible for the formation and allocation of bile and similar components;
3. the preservation of the location of all internal organs of a person provides the abdominal press. It is most relevant in a vertical position.

It should be noted that the internal organs have even more specific protection, namely such that is provided by the bones. From the back it is a vertebral pillar and pelvic bones, ahead is exclusively muscles. There are other forms of protection that allow you to worry and cope with any extreme situations and even injuries. It should also be noted that the fact that the structure of the internal organs in humans is correct is whether certain departments work correctly with ultrasound. It is this method that is 100% effective. On some differences between men and women in the structure of the internal organs of the abdominal cavity - hereinafter.

Differences in the structure of internal organs between men and women

Before switching to the features of the structure of the internal organs among male and female representatives, which are visible even in paintings, I would like to pay attention to some other moments. In particular, the fact that the characteristic feature of the structure of the abnormal organs should be considered a coating very thin serous shell. We are talking about mesothelial tissue, which has a significant amount of strong fibers.

In addition, mesothelium provides lubrication production, reduces the friction of the organs - precisely due to this feature, which is characterized by the structure of a person, we do not experience painful and just unpleasant sensations.

Such pains can only appear in diseases or inflammatory states, infectious lesions.

Speaking directly on female representatives, it is necessary to pay attention to the fact that one of the main differences is the presence in the field of small pelvis pipes, which communicate directly with the uterus. Through the vagina, the sexual sphere gets the opportunity to communicate with the external environment, which is obvious in the pictures. To fix certain internal female organs of the sexual system, as well as the prostate gland in men, it is possible to exercise an ultrasound of human peritoneum organs, which demonstrates some other departments.

If we say specifically about the organs of the abdominal cavity of male representatives, then they are located exclusively in a closed space. However, regardless of the sexual activity of a person, internal organs and their structure are always determined by the presence of a serous shell. The difference lies only in the one partially covered by the inner region or the film is located on the entire surface part.

In general, the placement of the organs of the peritoneum and space for the peritoneum is possible in three versions. The first is an extraperitoneal, which is characterized by the fact that the peritonean covers insides solely in front. It is characteristic of kidney. Further, to the second variant, specialists consider the mesoperitoneal, in the framework of the development of which only three sides of one or another inside possess the coating, and the fourth remains no coated. The most characteristic example is the liver, which is almost completely eliminated by a serous shell.

The third option is intraperitoneal, which is characterized by the imputation of the abdominal authority from all sides. Here, one of the examples can be considered the small intestine. About how the diagnosis of human internal organs is carried out, as their structure is determined and much more, further.

How is the diagnosis of abdominal organs?

In order to accurately determine the location and any other features of the abdominal organs in men and women, it is necessary to take care of the diagnostic survey. The main methodology is ultrasound, due to which, as the pictures are apparent, for example, the key causes of pain in the abdomen. In addition, the state of the gallbladder, the liver, is carried out, the pancreatic and aortic inspection is carried out.

The specialist gets the opportunity to visually make sure that there are stones in ducts with bile, is it possible to confirm the existing suspicion of ascites. In addition, it was the presented method of examination as in the pictures a organic kidney damage is detected and the sharp form of appendicitis. On the ultrasound ideally, it turns out to view the topography of the organs of the peritoneum.

In general, according to specialists, the procedure is completely harmless and safe, it is permissible to carry out enough often, due to the lack of influence of ultrasonic waves on the structural structure of cells.

To judge how correctly the peritoneum organs are located, the degree of development of pathological conditions can be determined by the exercise not only ultrasound, but also CT or MRI. The presented diagnostic techniques can easily identify focal lesions, as well as fat regeneration of liver, dystrophic and ischemic algorithms, which can become increasingly intense.

At the same time, for example, stones (deposits of calcium salts) on MRI snapshots and pictures can not be fixed. In the overwhelming majority of cases, their cost is approximately comparable to the implementation of the diagnostic survey through an ultrasound.

Considering all this, it is safe to argue that it is today that it is known to those skilled in the art about the structure of not only internal organs, but also all those structures that are included in the abdominal cavity. It is they who provide 100% coherent work of the body, fully providing all physiological processes.

1. Is it possible to prevent cancer?
The emergence of such a disease, as cancer, depends on many factors. To ensure full security can not be any person. But everyone can significantly reduce the chances of the appearance of a malignant tumor.

2. How does smoking affect the development of cancer?
Absolutely, categorically prohibit yourself smoking. This truth is already tired of everyone. But the rejection of smoking reduces the risk of developing all types of cancer. 30% of deaths from cancer are associated with smoking. In Russia, the tumors of the lungs kill more people than tumors of all other organs.
The exception of tobacco from his life is better prevention. Even if you smoke not a bundle a day, but only half, the risk of lung cancer is already dropped by 27%, as the American Medical Association found out.

3. Will the extra weight development of cancer?
See the scales often! Extra kilograms will affect not only the waist. The American Institute for Cancer Research found that obesity provokes the development of esophageal tumors, kidney and gallbladder. The fact is that the adipose tissue is not only for maintaining energy reserves, it also has a secretory function: fat produces proteins that affect the development of a chronic inflammatory process in the body. And oncological diseases just appear on the background of inflammation. In Russia, 26% of all cases of oncological diseases of WHO associates with obesity.

4. Do you have a sport to reduce the risk of cancer?
Pay training at least half an hour a week. Sports stands on one stage with proper nutrition when it comes to the prevention of oncology. In the United States, a third of all deaths are associated with the fact that patients did not comply with any diet and did not pay attention to physical education. An American oncological society recommends training 150 minutes a week at a moderate pace or two times less, but more active. However, the study published in the magazine Nutrition and Cancer in 2010 proves that even 30 minutes will be enough to reduce the risk of breast cancer (each eighth woman in the world) is 35%.

5. What affects alcohol on cancer cells?
Smaller alcohol! Alcohol accused of the occurrence of oral tumors, larynx, liver, rectum and dairy glazes. Ethyl alcohol decays in the body to acetic aldehyde, which then under the action of enzymes goes to acetic acid. Acetaldehyde is the strongest carcinogen. Alcohol is especially harmful to women, as it stimulates the production of estrogen - hormones affecting the growth of breast tissues. Excess estrogen leads to the formation of breast tumors, which means that every super sip of alcohol increases the risk of getting sick.

6. How does cabbage help to deal with cancer?
Love broccoli cabbage. Vegetables not only enter a healthy diet, they also help to fight cancer. Including therefore recommendations on healthy nutrition contain a rule: half of the day diet should be vegetables and fruits. Especially useful vegetables related to the cross-color, in which glucosinolates are contained - substances that, when recycling, acquire anti-cancer properties. These vegetables include cabbage: ordinary white, Brussels and broccoli.

7. During cancer of which organ affects red meat?
The more eat vegetables, the less put in a plate of red meat. Studies confirmed that people eating more than 500 g of red meat a week, above the risk of rack of the rectum.

8. What are the means from the proposed protect against skin cancer?
Fight sunglasses! Women aged 18-36 years old are especially susceptible to melanoma, the most dangerous of skin cancer forms. In Russia, only for 10 years, the incidence of melanoma grew by 26%, world statistics show even greater increase. This accuse equipment for artificial sunburn, and sun rays. Danger can be minimized using a simple tube sunscreen. The study of Journal of Clinical Oncology 2010 confirmed that people who regularly apply special creams sick melanoma are twice as fewer than those who neglect such cosmetics.
The cream should be chosen with the SPF 15 protection factor, to apply it even in winter and even in cloudy weather (the procedure should turn into the same habit as the cleaning of the teeth), and not substitute for the sun's rays from 10 to 16 hours.

9. How do you think whether stresses affect the development of cancer?
By itself, the stress of cancer does not cause, but he weakens the whole organism and creates conditions for the development of this disease. Studies have shown that constant concern changes the activity of immune cells responsible for the inclusion of the "Bay and Run" mechanism. As a result, the blood constantly circulates a large number of cortisol, monocytes and neutrophils that are responsible for inflammatory processes. And as already mentioned, chronic inflammatory processes can lead to the formation of cancer cells.

Know the structure and location of the internal organs is extremely important. If not even studying this question thoroughly, then at least a superficial understanding, where and how one or another is located is, it will help to freely navigate when painful sensations occur, and at the same time react. Among the inner, there are both the organs of the chest and pelvic cavity and the organs of the abdominal cavity of the person. The location of them, schema and general information are presented in this article.

Organs

The human body is the most complex mechanism consisting of a huge set of cells that form tissues. From individual groups, organs are obtained, which are called internally, since the location of the organs in humans is inside.

Many of them are known to almost everyone. And in most cases, while somewhere does not overtake, people tend to do not think about what they are inside. Nevertheless, even if the scheme is familiar to the arrangement of human organs only superficially, in case of illness, this knowledge will significantly simplify the explanation of the doctor. Also, the recommendations of the latter will become more understandable.

Organ system and apparatus

Under the concept of the system, a specific group of organs with the relationship of anatomical and embryological plans is implied, as well as performing a unified function.

In turn, the device, the bodies of which are closely interrelated, does not have kinship inherent in the system.

Splash

The study and location of organs in humans are considered anatomy in a special section, which is called consumer technology, the teachings on the courses. We are talking about structures that are in the cavities of the body.

First of all, these are the abdominal cavity organs participating in the digestion, the location of which is the following.

Next is the urinary, urinary and sexual system. Also in the section Endocrine glands, located next to these systems.

The internal organs also include the brain. In the cranial box is located the head, and in the spinal canal - the dorsal. But within the section under consideration, these structures are not studied.

All organs appear in the form of systems operating with full interaction with the whole organism. There are respiratory, urinary, digestive, endocrine, reproductive, nervous and other systems.

Man's location in humans

They are in several specific cavities.

So, in the chest, located within the borders of the chest and the upper diaphragm, are three others. It is a pelicard with a heart and two pleural on both sides with the lungs.

In the abdominal cavity there are kidneys, stomach, most of the intestines, liver, pancreas and other organs. It is a torso located below the diaphragm. It includes the abdominal itself and the pelvic cavity.

The abdominal is divided into the retroperitoneal space and the cavity of the peritoneum. The pelvic contains the excretory and reproductive system.

To understand even more detailed location of human organs, the photo below serves as a supplement to the above described. On one side, the cavities are depicted on one side, and on the other hand, the main bodies that are in them are.

The structure and scheme of human arrangement

The first in their tubes have several layers, which are also called shells. From the inside the mucous membrane is enjoyed, which plays mainly a protective function. Most organs on it have folds with outgrowths and deepening. But there are completely smooth mucous membranes.

In addition to them, there is a muscular shell with circular and longitudinal layers, separated by a connective tissue.

On the human body there are smooth and transverse muscles. Smooth - prevail in the respiratory tube, urinary organs. In the digestive tube, transverse muscles are located in the upper and lower departments.

In some groups of organs, there is another shell, where vessels and nerves pass.

All components of the digestive system and lungs have a serous shell, which is formed by a connective tissue. It is smooth, thanks to which there is a slight slip of the insides about each other.

Parenchimatous organs, unlike the previous ones, do not have cavities. They contain functional (parenchyma) and connecting (stromas) tissue. Cells performing the main tasks form a parenchyma, and the soft core of the organ is formed with stroma.

Men's and women's organs

With the exception of the genital, the location of human organs - both men and women - is the same. In the female organism, for example, there are vagina, uterus and ovaries. In men's - prostate gland, seed bubbles and so on.

In addition, men's organs are usually larger than women and weigh, respectively, more. Although, of course, it is found and on the contrary, when women have large forms, and men are small.

Sizes and functions

As the arrangement of human organs has its own characteristics and their size. Of the small, there are, for example, adrenal glands, and from large intestines.

As is well known from the anatomy and shows the location of the person's organs the photo above, the total weight of the internship can be about twenty percent of the entire body weight.

In the presence of different diseases, the size and weight can both decrease and increase.

The functions of the organs are different, but they are closely interconnected with each other. They can be compared with musicians playing on their tools under the control of the conductor - the brain. There are no unnecessary musicians in the orchestra. Also, however, and there is not a single unnecessary structure and system in the human body.

For example, due to breathing, digestive and excretory systems, the exchange is implemented between the external environment and the organism. The genitals provide reproduction.

All these systems are vital.

Systems and apparatus

Consider the overall features of individual systems.

Skeleton is a musculoskeletal system, which includes all bones, tendons, joints and somatic muscles. It depends on both the proportion of the body and movement and locomotion.

The location of the organs of the human cardiovascular system provides blood movement along the veins and arteries, the saturation of the cell by oxygen and nutrients, on the one hand, and deriving carbon dioxide with other exhaust substances from the body, on the other. The main body here is the heart that constantly pumps blood along the vessels.

The lymphatic system consists of vessels, capillaries, ducts, trunks and nodes. Under low lymph pressures move along the tubes, ensuring the withdrawal of waste of life.

All internal organs of a person, the location scheme of which is shown below, are regulated by means of a nervous system, which consists of central and peripheral departments. The main includes a spinal and brain. Peripheral consists of nerves, plexuses, roots, gangliy and nerve endings.

The functions of the system are vegetative (responsible for the transfer of pulses) and somatic (connecting the brain with skin and ODE).

The sensory system belongs to the main role for fixing the reaction to external stimuli and changes. It includes nose, language, ears, eyes and leather. Its occurrence is the result of the work of the nervous system.

Endocrine along with the nervous system regulates internal reactions and sensations of the environment. Emotions, mental activity, development, growth, puberty are dependent on her work.

The main bodies in it are the thyroid and pancreas, testicles or ovaries, adrenal glands, epiphysis, pituitary gland and thymus.

The reproductive system is responsible for reproduction.

The urinary system is completely in the pelvic cavity. She, like the previous one, differs depending on the floor. The need for the system is to withdraw toxic and alien compounds, an oversupply of various substances through the urine. The urinary system consists of kidneys, urethra, ureterals and bladder.

The digestive system is the internal organs of man in the abdominal cavity. The following scheme is as follows:

Its function, logical outgoing from the name, is to extract and deliver nutrients into the cells. The arrangement of human abdominal organs gives a general idea of \u200b\u200bthe process of digestion. It consists of mechanical and chemical processing of food, suction, splitting and removal from the body of waste.

The respiratory system consists of the upper (nasopharynx) and lower (larynx, bronchi and trachea) departments.

The immune system is the protection of the organism from tumors and pathogens. It consists of thymus, lymphoid fabric, spleen and lymph nodes.

Skin cover protects the body from temperature drops, drying, damage and penetrate pathogenic microorganisms and toxins. It consists of leather, nails, hair, sebaceous and sweat glands.

Internal organs - the basis of life

The photo presents the location of the internal organs of a person with a description.

It can be said that they are the basis of life. Without the lower or upper limbs, it is difficult to live, but still you can. But without a heart or liver, a person cannot live at all.

Thus, there are organs that are vital, and there are those without which life is difficult, nevertheless possible.

At the same time, some of the first components have a paired structure, and without one of them, the entire function goes to the remaining part (for example, kidneys).

Some structures are capable of regenerated (this applies to the liver).

Nature endowed the human body with the most complex system to which he should carefully relate and protect what he was given in the allotted period.

Many people neglect the most elementary things capable of maintaining the body in order. Because of this, he besides the time. There are diseases and a person leaves the life when he has not yet done all the cases that should have.

Each of the systems plays a huge role in human life, and the slightest violation of any of the bodies can lead to a significant deterioration in health and affect the quality of life as a whole.

The uniqueness of the human body consists in its harmonious and coordinated work, in which absolutely all organs and systems take part. The exclusiveness of this process is that a number of physiological processes occurs simultaneously, each of which is assigned an independent role. In view of this, organs that perform this or that purpose are combined into vital systems. For example, the digestive system ensures the human body with the necessary substances that come from food, the cardiovascular system is responsible for circulating blood and the flow of oxygen to the tissues, and without the full operation of the musculoskeletal system, the person will not be able to move normally.

Features of the structure of the skeleton of man

The skeleton of a person is a complex system consisting of bones of various shapes and sizes, each of which has a certain appointment.

For the full operation of the musculoskeletal system in the system there are bundles, joints, muscles, tendons and a number of other compounds that provide a person mobility.

In addition, the skeleton performs other functions, such as:

• protective;
• reference;
• Motor;
• bleale;
• shock-absorbing.

The skeleton of the newborn baby includes about 270 bones, some of which are growing over time. These bones include the bones of the skull, spine and pelvis. In the skeleton of an adult - 206 bones, but in some cases 205 or 207 may occur. Approximately the seventh of all bones belongs to the unpaired bones, the rest are paired.

The main feature of the structure of the skeleton of the human body is its separation on axial and additional. The bones included in the axial skeleton form its basis, the center of which is the spine. An equally important role in the bone system is played by a skull forming a head, and a protective protection for the brain. The chest, which, besides the protective functions of the internal organs, plays an important role in respiratory processes.

In the area of \u200b\u200bthe axial skeleton there is a number of vital organs, thanks to the work of which a person lives. But, besides this, a person needs to be operable, and carry out some manipulation by hand and legs. They are just forming an additional skeleton, which includes the upper and lower limbs, as well as the place of attachment of the limbs to the axial skeleton.

Man's skeleton structure with description

The structure of a human skull with a description

The skull is a combination of bones, forming a head frame, and an employee for protecting the brain. The bones of the cerebral department consist of such bones as a grip, lattice, frontal, dark, wedge-shaped, temporal.

For the facial part of the bone frame, the presence of the upper and lower jaws, on which the teeth are located, the sublard bone, as well as the cheek, tear, nasal bone, coulter and nasal sink. Practical All bone elements of the skull are connected by seams, except for the lower jaw, for which the presence of a larger joint is characteristic.

The structure of the spine of a person with the decoding of the vertebrae

The spine is a fundamental part of the skeleton of the person, to which a number of other bones are attached. It is characterized by special flexibility and strength, due to which a person can withstand significant physical exertion.

The vertebrae, from which the vertebral pole consists, are intergoned with intervertebral discs and ligaments. It is they that provide mobility of the compounds, and soften the pressure from physical exertion. In addition to the support and motor functions, the spine has protective features regarding the spinal cord. A lot of nerve endings are concentrated here who take part between the activities of the brain and other human bodies.

The spine includes 33-34 vertebra, which, in turn, are divided into the following departments:

1. The cervical department is the upper part of the spinal column, consisting of 7 vertebrae. Thanks to the atypical structure of the first two vertebrae, this area is the most mobile, which allows you to make moving heads in different directions.
2. Chest department. The ribs are attached to 12 vertebrae of this area of \u200b\u200bthe ridge. The chest, which they form, is a kind of frame to protect the respiratory organs. In view of this, this spine is characterized by increasingly.
3. Lumbar department. This part of the spine is susceptible to the maximum load that a person feels when walking, sports, as well as various positions of the body in which support is required. This explains the presence of vertebrae of larger sizes whose processes are directed backwards. The lumbar section of the pillar is somewhat bent, which allows you to withstand the pressure of the upper part of the human body.
4. Sleepy department. After the lumbar department, there is a cross, consisting of 5 vertebrae, and a triangular bone formed. The main purpose of the sacrilate department is the compound of the lumbar and bone of the pelvis.
5. Copchiki department. The lower part of the spinal column is a combination of 3-5 unforgettable vertebrae possessing the pyramidal form. This department has a distribution function, as a result of which the load on the pelvic bone system decreases.

Picture of a man's footage with description

The leg, or the lower limb is a pair body with supporting and motor functions. Since the legs throughout the human life are subject to a huge burden, nature provided them with largest bones, which are distinguished by a special strength and structure.

Anatomical structure of human feet:

1. The thigh is a compound of femur and a knee cup, which has a rounded form and protects the knee joint from injuries. The place of attachment of the hip to the bones of the pelvis is called a hip joint.
2. The shin is a part of the lower limb consisting of two berth bones and a patella. Small and large bone at the bottom of the foot are connected by ankle joint.
3. The foot is a set of many small bones, which form different parts of the feet - rear, medium and front. The arch or lifting of the foot belongs to the middle department, the heel - to the rear, the pad and fingers are part of the front of the foot.

The composition of the lower limbs is quite complicated in one foot contain 26 bones, taking into account the femoral, bertovy and patella - only 30. No less important component of the legs are the muscles, the largest number of which is in the hip region. Slightly less muscle compounds are in the area of \u200b\u200bthe pelvis and the tibia. In total, the muscular weight of the lower extremities occupies a part of the total muscular mass of the body, and contains 39 muscles.

Bone human hand

The complex structure of the upper limbs of a person is due to its comprehensive functionality.

The presence of numerous joints allows you to perform incredibly exact movements, bundles and tendons provide connecting functions, but the role of an additional support is assigned to the muscles.

Anatomical structure of the upper limb:

1. The shoulder belt is the scene of the arm and the chest, at the top of which the Suglob is connected to the clavicle. The second end of the bone is connected to the spatula, which provides mobility shoulders. This part of the limb is the most powerful, and is able to withstand significant loads.
2. Shoulder is a finiteness department consisting of a shoulder bone, from both sides of which are the joints - shoulder and elbow. In this section, the hands are undergoing superficial, elbow and radial nervous paths.
3. The forearm is the upper part of the limb that connects the elbow loss and wrist. The presence of 2 types of bones - radiation and elbow, makes it possible to raise gravity and engage in active sports.
4. The brush is connected to the forearm by the crew joint, and consists of 27 bones of small sizes. The upper finiteness department is a wrist consisting of 8 bones, 5 faded bones and the phalanx of the fingers. Each finger contains 3 phalanxes, except for large, in which only 2 bones are present.

The greatest amount of muscle compounds is in the forearm area, which allows to show the motor activity of the fingers and brushes. Tendons take direct participation in the development of joints, as well as the linking link between the bone system and muscle tissue, giving the hands of flexibility. The skin of the limbs performs the fungic and protection functions. The sensitivity of the epidermis provides many nerve fibers that are responsible for the reflex reaction of the muscles to one or another stimulus.

Description of the internal structure of human organs:

Each internal human body plays a huge role in leaking a huge number of physiological processes. The complexity and uniqueness of all departments consists in simultaneously performing many functions on which the human life depends.

brain

The human brain is one of the most unique bodies that makes great interest to scientists around the world. As a result of a huge number of research, many science figures are in search of effective methods of using the brain at full capacity. Despite the incredible abilities of this body, a person uses only a minor part of its resources.

The brain occupies the brain part of the skull, and as it takes it, it becomes its shape. The average weight of the brain tissue ranges from 1000 to 1800. In the female representatives, the brain mass is less than 100-200 g, compared with the male brain. The central organ of the nervous system consists of a brain barrel, cerebellum, left and right hemispheres. The bark of the head body is a bowl of gray substance that covers the brain surface. Inside the organ is a white mass consisting of neuron processes, with which information enters the neurons of the gray matter.

Among the huge number of functions that the central authority is endowed, it is worth noting the following:

• visiting
• auditory;
• Motor;
• respiratory regulation;
• motor;
• sensory;
• Coordination of movements.

the structure of the eye of man

The eye is a paired sensitive organ, the functional purpose of which is the perception of visual information.

The full operation of this body ensures the coordinated work of all its components - the optic nerve, eyeball, muscle tissue and eyelids. The movement of the eyeball is provided by the muscles that receive pulses from the brain with eye nerves. Eye muscle fibers are one of the most mobile in the human body, and allow many microdvitations to be performed only for the hundredth of a second.

the structure of the ear of man

Despite the simplicity of the mechanism of work of the ear, its structure cannot be called such, since the process involves a plurality of components. The main feature of the auditory body is the transformation of mechanical oscillations from the external environment into nervous impulses.

Anatomical composition of the ear:

• The inner ear is a combination of semicircular tubules, a webbed labyrinth and snail;
• The average ear, which includes a drum cavity, auditory bones and Eustachyeva pipe;
• Outdoor ear consisting of an auditory pass and ear shell.

structure of the throat of man

The throat plays one of the most important functions in the body, since it helps to promote oxygen into respiratory organs. Also through the throat, food enters the digestive organs, and the particular structure of the body prevents slices of food into the respiratory tract. This area belongs to the upper respiratory tract, which includes voice ligaments, muscle compounds, as well as vessels and nervous paths.

Anatomical composition of the throat:

• larynx;
• pharynx;
• Rotoglot;
• nasopharynx;
• trachea.

rib cage

The main purpose of the chest is the protection of internal organs and the spinal column of a person from mechanical damage and deformation.

In the region of the chest and abdominal cavity there is a diaphragm - a muscle contributing to the expansion of pulmonary fractions.

In the chest there are organs on which a person's life depends:

• -Serders, ensuring the operation of the circulatory system;
• lungs that are responsible for the flow of oxygen into human blood;
• -bross, contributing to the purification and passage of air to the respiratory organs;
• Milk iron - responsible for the state of the immune system

structure of the heart of man

The human heart is independent of the brain with the muscular organ, in the function of which includes blood circulation.

In addition, the heart muscle produces a hormonal substance that is responsible for normalization of fluid in tissue cells. The heart is located between the pulmonary lobes in the middle side of the chest, and its base is closer to the spine. The organ is connected to venous trunks, with the help of which the blood gets into the heart, and then in the artery. The ventricles and the atrium of the heart, connected by partitions, are separate cavities to which veins and arteries are adjacent.

the structure of light man

Lightweight is a pair body of the human body, which has a contractile, gas exchange and cleansing functions. Due to the active reduction movements, the lungs not only ensure the flow of oxygen in the body tissue and remove harmful substances, but also contribute to maintaining the necessary level of acid-alkaline and water balance.

The main feature of the structure of the respiratory body is an unequal number of parts - the left lung consists of two pieces, the right - of three. The lungs are covered with a special shell - pleutra, which forms a pleural bag, enveloping respiratory organs. The gas exchange processes of respiratory bodies occur in alveoli, which are formation of epithelial cells and capillaries.

These include:

• liver;
• stomach;
• kidney;
• adrenal glands;
• intestines;
• spleen;
• Gallbladder.

low pelvis organs

The internal organs of the small pelvis have excretory and reproductive purpose. For the structure of the female organism, the dense adjacent of all organs in this area is characterized by each other, which guarantees their full functioning. Also, the female organism differs from the male presence of the uterus - the mainly conducted organ, and the ovaries that are the source of the production of sex hormones. At the bottom of the pelvis, both sexes are a bladder and ureterals. For male representatives, the presence of prostate gland and seed bubbles, which participate in the reproductive processes of the body.
