Sound of the heart valves closing in a healthy 16 year old girl. The stethoscope is at the tricuspid area.
A heart valve (cardiac valve) is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side.
