Which valve separates the right atrium from the right ventricle?

Giải thích

The tricuspid valve, named for its three cusps, lies between the right atrium and right ventricle and prevents backflow during ventricular systole. The mitral valve is the corresponding atrioventricular valve on the left side. The pulmonic and aortic valves are semilunar valves that guard the exits from the right and left ventricles.
