The aim of the draft structure of the course of the functions of live animals, according to the foundation to explain the evolutionary steps. Most of the basic secrets physiology, cellular and molecular level in recent years with many new techniques have been developed. Therefore, the principle of molecular physiology and physical terms, many born in the ability to express. Transport of substances in the cell, chemical structures, digestive, respiratory, circulatory, excretory systems, and also move the muscles and physiology, aimed to explain the physiology of sensory and nervous.
