The video explains the heart's function, pumping five liters of blood per minute and enough to fill a train car daily. It describes the heart's structure, including four chambers and the septum. Blood flow is detailed, showing how oxygen-depleted blood travels from the body to the right atrium, then to the lungs for oxygenation, and back to the left atrium and ventricle to be pumped throughout the body. The coronary arteries supply the heart with blood, crucial for its health.
