The main method of cognition of the performance of biological systems is their mathematical modeling. The essence of this method should reflect the principle of optimization in biology[9]. Any biosystem cannot function if its energy consumption is inadequately high. The same is applicable to the blood circulatory system. Its main function is to transport blood throughout the body in order to maintain the proper gaseous exchange, deliver important substances to viscera and tissues in living body and remove decay products. It is impossible to study this function without due consideration of hemodynamic features. But how is the blood circulation provided? It is a question of principle, and so.
