I WONDER - What Does The Heart Do?

The video explains the heart's role in circulating blood throughout the body. It highlights that the heart beats approximately 115,000 times daily, pumping around 2,000 gallons of blood. The right side of the heart sends blood to the lungs for oxygenation, while the left side circulates oxygen-rich blood back to the body, ensuring muscles receive necessary oxygen.
