The heart's primary function is to pump oxygen-rich blood to the body and oxygen-poor blood to the lungs. It has four chambers: the right atrium, right ventricle, left atrium, and left ventricle. The cardiovascular system, which includes arteries and veins, delivers oxygen, nutrients, and hormones to cells and organs, playing a crucial role in activity, exercise, and stress management. Cardiologists specialize in the treatment of heart and vascular diseases.
