Which chamber is separated from the left ventricle by the bicuspid valve?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Chordae tendinae

Answer: (A)

The space between the left atrium and the left ventricle is separated by the mitral (bicuspid) valve. This valve allows oxygenated blood to flow from the left atrium into the left ventricle during diastole and prevents backflow when the left ventricle contracts. The left atrium receives blood from the lungs via the pulmonary veins, then passes it through this valve to the left ventricle, which then pumps it to the rest of the body. While the right atrium is separated from its ventricle by the tricuspid valve, and the chordae tendineae are tendinous cords supporting the valve leaflets, not chambers, the correct chamber separated from the left ventricle by the bicuspid valve is the left atrium.
