Physiology is the science dealing with life processes of animals and human beings, i.e. the study of function and regulation of physical and chemical processes in living cells and multicellular organisms. The mechanisms for regulation and integration of functions due to changes in inner or outer milieu is emphasized.
Physiology is a basic discipline of medicine, odontology and biology.
Physiological research is based on experiments on intact animals, on living organs or cells and their organelles. Knowledge of physiology is necessary for understanding important public health problems connected to changes in environment, nutrition, work, sleep, behavior etc. Therefore, such knowledge is increasingly used in private and public sectors outside school and universities.
