The human heart consists of four chambers: two atria (the upper chambers) and two ventricles (the lower chambers). The right atrium receives deoxygenated blood from the body, which then moves to the right ventricle, where it is pumped to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs, which flows into the left ventricle, where it is then pumped out to the rest of the body. This chamber arrangement is essential for efficient blood circulation.
