The mitral valve has fewer flaps than the right atrioventricular valve.<br> a. True<br> b. False
kolezko [41]

Answer:

The mitral valve has fewer flaps than the right atrioventricular valve:

<em>a) True </em>

Explanation:

The mitral valve is a bicuspid valve, which means it has two flaps; whereas, the right atrioventricular valve is a tricuspid valve and so has three flaps.

These two heart valves link the atrium with the ventricles. The mitral valve is located on the left side of the heart, while the tricuspid valve is on the right side.
