What is the muscle that pumps bloo thoghout your body?

The muscle that pumps blood throughout your body is the heart. It is a muscular organ that contracts rhythmically to circulate oxygen-rich blood from the lungs to the rest of the body and return deoxygenated blood back to the lungs for reoxygenation. The heart consists of four chambers: the left and right atria and the left and right ventricles, each playing a vital role in this process.
