What ensures the movement of blood in the body?

The governing mechanism of blood circulation is the heart, which consists of 4 chambers. Atria, ventricles, right and left. The ventricles are larger than the atria and have well-developed smelt muscles (because they displace blood).
The following valves are responsible for regulating the displacement of blood: cuspid valves (give a course for the direction of blood from the atria to the ventricles); lunar (draw blood from the ventricles into the vessels).
