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

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

• A. Bicuspid Valve
• B. Semilunar Valve
• C. Cardiac Conduction System
• D. Movement of blood

Answer: (A)

Valves control one-way flow of blood in the heart. Between the left atrium and left ventricle lies the left atrioventricular valve, the mitral valve (also called the bicuspid valve) because it has two cusps. This valve opens to allow blood to move from the atrium to the ventricle during relaxation, and it closes when the ventricle contracts to stop blood from flowing back into the atrium. The semilunar valve is located between the left ventricle and the aorta, not between the atrium and ventricle. The cardiac conduction system is the heart’s electrical pathway, not a valve. Movement of blood describes flow, not a valve.
