What valve is between the right atrium and right ventricle?

Explanation:
The valve between the right atrium and right ventricle is the tricuspid valve. It is an atrioventricular valve with three cusps that opens to let blood flow from the right atrium into the right ventricle, and it closes during ventricular contraction to prevent backflow into the atrium. The left side has the mitral (bicuspid) valve between the left atrium and left ventricle, while the two semilunar valves sit at the outlets of the ventricles—one between the left ventricle and the aorta, and the other between the right ventricle and the pulmonary artery.
