The Right atrioventricular valve (also known as the Tricuspid Valve) has 3 FLAPS.
Atrioventricular (AV) Valves Separate atria from the ventricles, allow blood to flow from the atria to the ventricles and prevent flow in opposite directions. The right AV valve is called the tricuspid valve. The left AV valve is called the mitral valve. When ventricles relax, atrial pressure is higher so valves open.
