Which valves are the atrioventricular valves?

Atrioventricular valves sit between the atria and ventricles and prevent backflow into the atria when the ventricles contract. The right-sided AV valve is the tricuspid, and the left-sided AV valve is the mitral. These valves are anchored by chordae tendineae and papillary muscles, which help keep them from billowing backward during systole. By contrast, the aortic and pulmonary valves are semilunar valves between the ventricles and the great arteries, and they prevent blood from flowing back into the ventricles. So the valves that are between the atria and ventricles are the tricuspid and mitral.
