The Right atrioventricular valve (also known as the Tricuspid Valve) has 3 FLAPS.
1 Between each chamber of the heart are valves which prevent the blood being forced back into the chamber from which it was just pushed out. 2  Between the atria and the ventricles are the tricuspid and mitral valves (mitral is on the left and tricuspid on the right). 3  These are known as the atrioventricular valves.
