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, enough generalized knowledge. They will make it easy to navigate in various situations when pain occurs. Among the organs there are those that relate to the thoracic and pelvic area. Others are located in the abdominal cavity. Next, we consider the structure of man 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 located outside and inside. Some of them are known to every person. However, it should be noted that until the patient begins to hurt something, 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 discussed in this article, then it is possible to facilitate the diagnosis of many diseases.
There are systems in the body that have received a specific function. It should be noted: even though the bodies are united, they are not related.
Splanchnology
In order to understand the subtleties of this issue, the article describes the structure of the internal organs of a person. Photos are also attached to facilitate perception. It is necessary to pay attention to the concept, which reveals all issues related to the insides. The science of body cavities is called splanchnology.
The system of organs of the abdominal cavity includes several different structural units: the intestine, pancreas, stomach, liver, diaphragm, and gall bladder. Also in this list should be added anus.
There are still urinary, urinary and reproductive systems. This section of the 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, with the back in the spine. However, these structures are not studied in splanchnology sections.
Most of the organs form a certain system, which functions together with the whole organism. There is digestive, endocrine, reproductive, nervous, and so on.
Location of organs
Human internal organs, photos of which are presented in the article, are located in certain cavities. For example, in the chest, you can find the chest, 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 cavity. There are also reproductive systems.
Structure
Human internal organs are divided into some categories, for example, there are smooth, parenchymal and dense.
If we talk about the first, then they are created from several layers, which doctors call the 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 indentations. However, there are also smooth mucous membranes. On some organs there is muscle tissue that has received a longitudinal layer. It is separated by connective tissue. A person necessarily has smooth and striated muscles.
The first type, as a rule, is located in the genitourinary organs, and also in the respiratory tube. The second are localized in the upper and lower parts of the body. Also, some groups have a special membrane consisting of vessels and nerves.
The digestive system and all its organs received a serous coating, which is formed using connective tissue. Due to the fact that they are smooth, all the insides can easily rub against each other.
Parenchymal organs have no cavity. They consist of parenchyma and stroma tissue.
Functionality and Dimensions
All internal organs of a person have not only a special arrangement, but also functionality. If we talk about size, that is, small organs, for example, the adrenal glands. Of the large ones, the intestines. If you recall the short course of anatomy at school, you can see that the total weight of all the insides 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 is able to decrease or increase.
All organs perform different functions, but they are interconnected with each other. Many draw an analogy with musicians in an orchestra who play under the direction of a conductor. The last in the body is the brain. There are no unnecessary musicians in the orchestra, and so there are no unnecessary organs in the human body. The body implements all the vital functions.
System and apparatus
In addition, the features of certain systems should be considered. For example, the skeleton is a musculoskeletal system that consists of tendons, bones, joints and muscles. It depends on him the proportions of the body, as well as how a person will move.
In the cardiovascular system there are organs that provide blood movement, 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 of vessels, trunks, capillaries and so on. Due to the presence of a small pressure, the fluid moves through the tubes without any problems. This system is responsible for removing waste 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 able to exist without limbs, but this is impossible without a liver or heart. Accordingly, there are bodies that provide vital functions, 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 such are the kidneys. The human body is a rather complex system, so people must take care of it and monitor the condition. Do not neglect basic things, you should maintain your body in order. Otherwise, ahead of time, he will begin to wear out. The article provides a photo with a description of the internal organs of a person, which will allow better understanding of such a question.
