This is an animated video explaining how the human heart circulates blood.
The heart pumps 5 quarts of blood every minute and it beats 100,000 times every day.
The animation also explains how the lungs oxygenate the blood and purify it. You can
also understand the concept of systole, diastole and parts of the heart like atrium,
ventricles and so on.
