HEARTBEAT

There are two phases of the heartbeat. These phases are called diastole (relaxation) and systole (contraction). During diastole, the atria of the heart fill with blood from the venae cavae and the pulmonary vein. At the end of diastole, the atria contract and force blood into the ventricles through the tricuspid and mitral valves.

HEARTBEAT

There are two phases of the heartbeat. These phases are called dicistole (relaxation) and systole (contraction). During diastole, the atria of the heart fill with blood from the venae cavae and the pulmonary vein. At the end of diastole, the atria contract and force blood into the ventricles through the tricuspid and mitral valves.
