Which valves are the atrioventricular (AV) valves?

Explanation:
Valvular anatomy: the atrioventricular valves are the ones between the atria and the ventricles. On the right side lies the tricuspid valve, and on the left side lies the mitral valve. The aortic and pulmonary valves are not AV valves; they’re semilunar valves between the ventricles and the great arteries. The AV valves open during diastole to allow ventricular filling and close during systole to prevent blood from flowing back into the atria, with chordae tendineae and papillary muscles helping keep them from prolapsing. So the valves that fit this category are the tricuspid and mitral.
