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

Answer: (A)

The valve between the left atrium and left ventricle is the mitral valve. It sits on the left side of the heart and lets blood move from the atrium into the ventricle when the heart relaxes, then seals during contraction to prevent blood from flowing backward into the atrium. The mitral valve is also known as the bicuspid valve because it has two leaflets. The other valves correspond to other chamber connections: the tricuspid valve between the right atrium and right ventricle, the aortic valve between the left ventricle and the aorta, and the pulmonary valve between the right ventricle and the pulmonary artery.
