The Function of the Heart in the Circulatory System

The heart plays a crucial role in the circulatory system by pumping blood throughout the body. This vital organ ensures that oxygen and nutrients are delivered to the cells, while also removing carbon dioxide and other waste products. The heart consists of four chambers - the left and right atria, and the left and right ventricles. It works as a double pump, with the right side receiving deoxygenated blood from the body and sending it to the lungs for oxygenation, while the left side receives oxygenated blood from the lungs and pumps it out to the rest of the body.
