In anatomy, the heart valves are valves in the heart that maintain the unidirectional flow of blood by opening and closing depending on the difference in pressure on each side. The mechanical equivalent of the heart valves would be the reed valves.
There are four valves of the heart (not counting the valve of the coronary sinus and valve of the inferior vena cava
The two atrioventricular (AV) valves ensure blood flows from the atria to the ventricles, and not the other way.
The two semilunar (SL) valves are present in the arteries leaving the heart, and they prevent blood flowing back from the arteries into the ventricles.
The sound of the heart valves shutting is causes the heart sounds.
