Heart Contraction and Blood Flow - NHLBI, NIH The animation below shows how your heart pumps blood. Click the "start" button to play the animation. Written and spoken explanations are provided with each frame. The animation shows how blood flows through the heart as it contracts and relaxes. Heartbeat Almost everyone has heard the real or recorded sound of a heartbeat. A heartbeat may seem like a simple, repeated event. Each side of your heart uses an inlet valve to help move blood between the atrium and ventricle. Each of your heart's ventricles also has an outlet valve. Each heartbeat has two basic parts: diastole (di-AS-toe-lee) and systole (SIS-toe-lee). During diastole, the atria and ventricles of your heart relax and begin to fill with blood. The atria then begin to relax. Pumping Action Your heart uses its four valves to ensure your blood flows in only one direction. Each valve has a set of flaps called leaflets or cusps that seal or open the valve. Oxygen-poor blood from the vena cavae fills your heart's right atrium.
