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

• A. Tricuspid
• B. Pulmonary semilunar valve
• C. Bicuspid valve
• D. Chordae tendinae

Answer: (A)

This question tests your understanding of heart valves and where they are located. The valve between the right atrium and the right ventricle is the tricuspid valve. It is an atrioventricular valve that has three leaflets and opens to allow blood to flow from the right atrium into the right ventricle, then closes to prevent backflow during ventricular contraction. The other options aren’t between the right atrium and right ventricle: the pulmonary semilunar valve sits between the right ventricle and the pulmonary artery, stopping backflow into the ventricle after it’s pumped to the lungs; the bicuspid (mitral) valve sits between the left atrium and left ventricle; and the chordae tendineae are the tendinous cords that anchor the valve leaflets to papillary muscles, not a valve themselves.
