The atlas not only gives ideas about the functions of the body, but also shows the mechanisms of these functions at the organ, tissue, cellular, membrane and molecular levels, set out on the basis of modern scientific ideas. The content of the atlas corresponds to approximate physiology programs. The atlas includes 10 main sections on physiology (general physiology of excitable tissues, secondary messengers, synapse physiology, muscle physiology, physiology of the nervous system, cardiovascular system, breathing physiology, blood physiology, excretory system and digestive physiology).
