Which valve connects the atria and ventricles?

• A. Atrioventricular Valve
• B. Semilunar Valve
• C. Tricuspid Valve
• D. Pulmonary Valve

Answer: (A)

The valve category that connects the atria to the ventricles is the atrioventricular valve. These valves sit between each atrium and its corresponding ventricle and include the tricuspid (right side) and mitral (left side) valves. They open to allow blood to flow from the atria into the ventricles when the heart fills, then close during ventricular contraction to prevent backflow into the atria. Semilunar valves, by contrast, lie between the ventricles and the great arteries (aorta and pulmonary artery) and do not connect atria to ventricles. So the general term for the valves that bridge the atria and ventricles—an atrioventricular valve—is the best answer.
