An inset highlights cardiac muscle tissue, showing myocytes and intercalated disks. — human cardiovascular system The human heart is both a pump and a muscle. Its four chambers move blood efficiently, while cardiac muscle cells joined by intercalated disks synchronize each contraction.

It serves as an atrioventricular valve, functioning to allow blood to flow in only one direction—from the left atrium into the left ventricle—while preventing backflow during ventricular contraction.123
