The heart has four chambers: the right atrium, right ventricle, left atrium, and left ventricle. The right atrium receives deoxygenated blood from the body and sends it to the right ventricle, which pumps it to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs and transfers it to the left ventricle, which then pumps it out to the rest of the body. Each chamber plays a crucial role in maintaining the circulation of blood throughout the body.
