Which valve is located between the right atrium and the right ventricle?

• A. Aortic Valve
• B. Pulmonary Valve
• C. Mitral (Bicuspid) Valve
• D. Tricuspid Valve

Answer: (D)

The valve between the right atrium and right ventricle is the tricuspid valve. It’s the right-sided atrioventricular valve that opens to let blood move from the atrium into the ventricle during heart relaxation, and closes to prevent backflow during ventricular contraction. The tricuspid valve has three cusps—anterior, posterior, and septal. In contrast, the aortic valve sits between the left ventricle and the aorta, the pulmonary valve between the right ventricle and the pulmonary artery, and the mitral valve sits between the left atrium and left ventricle.
