What is the function of the heart?

The heart is a muscular organ whose main function is to pump blood throughout the body. It acts as the central organ of the circulatory system.

The heart continuously pumps oxygen-rich blood to different body tissues through arteries and receives oxygen-poor blood back through veins.

By maintaining blood circulation, the heart ensures that cells receive oxygen, nutrients, and hormones while waste products like carbon dioxide are transported for removal.

The heart also helps maintain blood pressure and supports the proper functioning of all body organs.

Its continuous pumping action is essential for sustaining life and maintaining overall body functions.
