Chambers and valves of the heart - Mayo Clinic
8 Oct 2024 at 10:51am
A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The heart valves are gates at the chamber openings. They keep blood flowing in the right direction.

If your heart valve can't be repaired and other treatments aren't an option, the valve might need to be replaced.

Valves made from living tissue are called biological tissue valves.

The heart's electrical system typically controls the heartbeat. Electrical signals, called impulses, move through the heart chambers. They tell the heart when to beat. Changes in heart signaling may happen if the heart muscle is damaged. Heart signaling problems also may be caused by changes in genes before birth or by using certain medicines.
