Which two valves are associated with the left ventricle?

• A. Bicuspid and Aortic semilunar valves
• B. Tricuspid and Pulmonary semilunar valves
• C. Aortic semilunar and Tricuspid valves
• D. Bicuspid and Tricuspid valves

Answer: (A)

Two valves are associated with the left ventricle. The bicuspid valve (also called the mitral valve) sits between the left atrium and left ventricle and controls blood flow into the ventricle, preventing backflow into the atrium when the ventricle contracts. The aortic semilunar valve sits between the left ventricle and the aorta and opens to eject blood into the systemic circulation, while preventing backflow from the aorta. The other valves belong to the right heart or connect different chambers, so they are not the ones associated with the left ventricle.
