What is the valve between the left atrium and the left ventricle of the heart?

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

Answer: (B)

The valve between the left atrium and left ventricle is the mitral valve. It opens to allow blood to move from the left atrium into the left ventricle as the heart fills, and it closes when the ventricle contracts to prevent blood from flowing backward into the atrium. This unidirectional flow is essential so that blood is pushed forward into the aorta through the aortic valve. The aortic valve is between the left ventricle and the aorta, the tricuspid valve sits between the right atrium and right ventricle, and there isn’t a standard coronary valve.
