Which valve is between the right atrium and right ventricle?

• A. Tricuspid valve
• B. Mitral valve
• C. Aortic valve
• D. Pulmonary valve

Answer: (A)

The tricuspid valve is the one between the right atrium and right ventricle. It’s the right-sided atrioventricular valve with three leaflets that opens to allow blood to flow from the atrium into the ventricle during diastole, and then closes to prevent backflow when the ventricle contracts. The other valves are located elsewhere: the mitral valve sits between the left atrium and left ventricle, the aortic valve sits between the left ventricle and the aorta, and the pulmonary valve sits between the right ventricle and the pulmonary artery.
