What is physiology

Physiology and biological science that studies the functioning of a healthy body and its parts - systems, organs, tissues, cells.
Physiology is divided into public and private. General physiology research of principles of activity of excitable tissues, the laws of their anger, excitement, etc. Private physiology studies inebriate the various bodies and their interaction in the system organizations of the whole organism. Physiology also includes such topics as comparative physiology, physiology of labour, sports, aviation and space physiology, clinical physiology and other
Functional changes of the organism for painful processes studies of pathological physiology (see).
Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Physiology has traditionally been divided between physiology of plants and animals, but the principles of physiology are universal, no matter what kind of body is studied. For example, what is known about the physiology of yeast cells can also be applied to human cells.
In this section we are in a popular form will study the basics of physiology.
In our time, everyone needs to know how and how his body. It is especially important that those engaged in sports. Because the human body is very complex biological system in which each organ has a specific function, but in General they all work in perfect harmony. But if one of the links of this established system fails, it violated the overall consistency and there comes the disease. In the section "human Physiology" designed for a wide range of readers, we popularly will tell how "lives and works" the human body, and that is in violation of its functions.

Over the last 20 years, physiology of animals and humans has been enriched thanks to the improvement of old and application of new research methods such number of important facts that it took a radical revision of previously existing theoretical concepts about the nature and mechanism of implementation of the various physiological processes. Naturally, published earlier textbooks physiology, including written E. B. Babsky, N. K. Vereshchagin, A. A. Zubkov, N. Century Timofeyev "the Rate of normal physiology", are outdated.
Initially we supposed to be limited to the processing of previously published textbook. However, soon it became clear to us that is required to write an entirely new text, as the old tutorial does not correspond to modern level of science. Had significantly change and shared the partition plan, and construction of the individual chapters, and logic of presentation of the material.
Time has changed and our writing team. The death of two authors - professors N. K. Vereshchagin and Professor N. Century Timofeeva - was to us a heavy loss. They were participants of the creation "of Course, normal physiology" and put a lot of creative work, the results of which were reflected in this section. In the group of authors included Professor G. I. Kosicky and doctor of medical Sciences B. I. Khodorov. To work on the head "Touch functions of the Central nervous system and regulation of movements" was engaged doctor of medical Sciences P. A. Durinyan.
In the work on the section of invaluable help to the authors had the editors of the publishing house "Medicine" - Professor A. C. Gubar and Professor C. L. Gubar. They are the authors bring their deep gratitude.
We will be grateful to readers, especially professors of medical institutes for critical remarks and advice they discovered flaws in the section.

General laws of physiology and basic physiological concepts

The functions of the body
The subject of physiology are functions of a living organism and its parts. So, getting to the statement of physiology, we must first stop on the concepts of "the body" and "function".
