The physiology

The physiology - the science of the life of organisms. Physiologists are interested in the processes occurring throughout the body and in its individual systems, organs, tissues, cells. How are these processes regulated? How do they change depending on the behavior of the organism in different conditions of its environment? Physiology studies the basic quality of the living - its vital functions, its functions and properties, both in relation to the whole organism, and in relation to its parts. In the basis of ideas about life activity are knowledge about the processes of metabolism, energy and information. Life activity is aimed at achieving a useful result and adaptation to environmental conditions.

The physiology is the science of the life of organisms

Any organism lives in a certain environment and accordingly all its organs react in one way or another to what is happening around. Physiology studies the phenomena traced in the body as a function of age, the general patterns of organisms, their responses to external stimuli. She often solves concrete, practical questions and tasks: reveals the processes that take place in the body during work, rest, nutrition, playing sports. As early as 1725, the Department of Anatomy and Physiology was established in the Academy that was opened in St. Petersburg. The world knows the names of Russian and Soviet physiologists: M.V. Lomonosov, I.P. Pavlov, I.M. Sechenov, A.A. Bogomolets, P.K. Anokhin, S.P. Botkin, K.A. Timiryazev, A.S. Famintsyn, S.P. Kostychev, and others.

Physiology includes several separate interrelated disciplines. Molecular physiology studies the essence of life and life at the level of molecules from which living organisms are composed. The physiology of the cell explores the vital activity of individual cells and, together with the molecular, are the most common disciplines of physiology, since all known forms of life exhibit all the properties of the living only within cells or cellular organisms. The physiology of microorganisms studies the patterns of life microbes. Plant physiology is closely related to the anatomy of plants and studies the vital features of the organisms of the plant world. The physiology of fungi studies the life of fungi. The physiology of man and animals is a logical continuation of the anatomy and histology of humans and animals and has a direct relationship to medicine.
