The Right atrioventricular valve (also known as the Tricuspid Valve) has 3 FLAPS.
Best Answer: The Atrioventricular Valves consist of the bicuspid valve (left side of the heart) and the tricuspid valve (right side of the heart). They allow flow of blood from the atria to the ventricles, and interesting the sound of the valves closing (along with the semilunar valves) is what the sound is in a heartbeat. The valves open and closed based on the pressure in the chambers of the heart.
