Which heart valve has leaflets described as "anterior, left and right"? Aortic Pulmonary Left atrioventricular Right atrioventricular

The heart valve that has leaflets described as "anterior, left and right" is the Right atrioventricular valve, also known as the tricuspid valve. Here are the steps to understand why:

1. The heart has four valves: the aortic valve, the pulmonary valve, the left atrioventricular (or mitral) valve, and the right atrioventricular (or tricuspid) valve.

2. The aortic and pulmonary valves are semilunar valves. They each have three small leaflets or cusps, but these are not typically referred to as "anterior, left and right".

3. The left atrioventricular valve, also known as the mitral valve, has two leaflets or cusps. Therefore, it cannot be the valve described as having "anterior, left and right" leaflets.

4. The right atrioventricular valve, also known as the tricuspid valve, has three leaflets or cusps. These can be described as "anterior, left and right", making it the valve that fits the description.
