Which valve separates the right atrium from the right ventricle?

Which valve separates the right atrium from the right ventricle?

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

Answer: (A)

Understanding how heart valves direct blood flow between chambers. The valve between the right atrium and the right ventricle is the tricuspid valve. It opens to allow blood to move from the atrium into the ventricle and closes during ventricular contraction to prevent backflow into the atrium. The left-side counterpart between the left atrium and left ventricle is the mitral valve, while the exit valves are the aortic valve (from the left ventricle to the aorta) and the pulmonary valve (from the right ventricle to the pulmonary artery). So, the valve that separates the right atrium from the right ventricle is the tricuspid valve.
