It is very important to know the location of all the internal organs of a person. There is no need to carefully study this issue, generalized knowledge is enough. They will allow you to easily navigate in various situations when pain occurs. Among the organs there are those that belong to the chest and pelvic region. Others are located in the abdominal cavity. Next, consider the human structure and internal organs. Photos of clarifying schemes are available in the article.
Description of organs
The human body is a complex mechanism that consists of cells, tissues, organs, outside and inside. Some of them are known to everyone. However, it should be noted that until the patient starts to get sick, he will not think about the state of his body. If you know where the various internal organs of a person are located, the structure of which is considered in thisarticle, it is possible to facilitate the diagnosis of many diseases.
There are systems in the body that have received a certain function. It should be noted that even though the organs are united, they are not related.
Splanchnology
In order to understand the subtleties of the issue under consideration, the article provides a description of the structure of the internal organs of a person. Photos are also attached for ease of understanding. It is necessary to pay attention to the concept that reveals all issues related to the insides. The science of body cavities is called splanchnology.
The abdominal system includes several different structural units: intestines, pancreas, stomach, liver, diaphragm and gallbladder. Anus should also be added to this list.
There are also genitourinary, urinary and reproductive systems. This section of anatomy studies the endocrine glands that are nearby. The brain should also be attributed to the internal organs of a person. The head is located in the skull, the back is located in the spine. However, these structures are not studied in the sections of splanchnology.
Most of the organs form a certain system that functions together with the whole body. There are digestive, endocrine, reproductive, nervous and so on.
Location of Organs
The internal organs of a person, the photos of which are presented in the article, are located in certain cavities. For example, in the chest one can find the thorax, the upper diaphragm, as well as the heart and two pleural branches. The stomach, kidneys, intestines, liver, pancreas and other organs are located in the abdominal region. They represent the body, which is located below the diaphragm. Thus, the described structure combines the abdominal and pelvic cavities. There is also a reproductive system.
Building
Human internal organs are divided into some categories, for example, there are smooth, parenchymal and dense.
If we talk about the first ones, they are created from several layers, which doctors call shells. As a rule, such organs are covered with a special mucous surface that performs a protective function. Most of the organs have a similar coating in the form of folds, where there are outgrowths and depressions. However, there are also smooth mucous membranes. Some organs have muscle tissue that has received a longitudinal layer. It is separated by connective tissues. A person necessarily has muscles of a smooth and striated appearance.
The first type, as a rule, is located in the urogenital organs, and also in the breathing tube. The latter are localized in the upper and lower parts of the body. Also, some groups have a special shell, consisting of vessels and nerves.
The digestive system and all its organs received a serous coating, which is formed with the help of connective tissues. Due to the fact that they are smooth, all the insides can easily rub against each other.friend.
Parenchymal organs do not have any cavity. They consist of parenchyma and tissue stroma.
Functionality and dimensions
All internal human organs have not only a special location, but also functionality. If we talk about size, then there are small organs, for example, the adrenal glands. Of the large ones - the intestines. If you recall a short course in anatomy at school, you will notice that the total weight of all the viscera can sometimes reach 20% of the total body weight. If we are talking about a person who has acute or chronic diseases, then this indicator can decrease or increase.
All organs perform different functions, but they are interconnected with each other. Many draw an analogy with the musicians in the orchestra, who play under the baton of a conductor. The last thing in the body is the brain. There are no unnecessary musicians in the orchestra, so there are no unnecessary organs in the human body. All vital functions are implemented in the body.
System and apparatus
Besides this, the features of certain systems should be considered. For example, the skeleton is the musculoskeletal system, which consists of tendons, bones, joints, and muscles. It is on him that the proportions of the body depend, as well as how a person will move.
In the cardiovascular system there are organs that provide the movement of blood, which allows you to saturate the cells with oxygen. The most important thing in this system is the heart, which pumps blood.
The lymphatic structure consists ofvessels, trunks, capillaries and so on. Due to the presence of a small pressure, the liquid moves through the tubes without problems. This system is responsible for removing waste products from the body.
All internal organs are regulated by the National Assembly, which is divided into 2 types: central and peripheral. The most important in the first system are the brain and spinal cord. The peripheral one consists of nerves, endings, and so on.
Necessity
Internal organs are the basis of life. A person is capable of existing without limbs, but without a liver or heart, this is impossible. Accordingly, there are organs that provide vital activity, as well as those that can be dispensed with. Certain structures are able to regenerate, for example, the liver. There are also organs whose function is performed by paired structures. An example of these are the kidneys. The human body is a rather complex system, so people must take care of it and monitor its condition. Do not neglect elementary things, you should keep the body in order. Otherwise, it will start to wear out ahead of time. The article contains photos describing the internal organs of a person, which will allow you to better understand this issue.
