Question

Which valve is present betwen the left atrium and ventricle?

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

Answer 1

The correct option is B Mitral

Valves are the membranous structure that prevents the backflow of the blood. The left atrioventricular valve is the 'bicuspid valve', but it is usually referred to as the 'mitral valve'. It has two rather heavy cusps, that permit blood to flow freely from the left atrium into the left ventricle. However, the cusps close when the left ventricle begins to contract; this prevents blood from returning to the left atrium and ensures the forward flow of blood into the aorta.

So, the correct answer is option B.
