The circulatory system is unique among the other systems in mammalians in having a single, mechanical mission — setting blood in motion. In such a simple hydraulic mechanism a pump and an energy source are needed to fulfill the requirements. The heart is the basic unit in the system, although it is helped by a specific construction and function of the peripheral vascular channels to achieve blood propulsion through a high-resistance network of nonrigid tubes.
