What is the name of the right atrioventricular valve?

The right atrioventricular valve is known as the tricuspid valve. This valve is located between the right atrium and the right ventricle of the heart. Its primary function is to prevent backflow of blood from the ventricle into the atrium during ventricular contraction. The name "tricuspid" refers to its three leaflets or cusps that open and close to facilitate the flow of blood in a one-way direction.

In the context of the other options, the aortic valve is located between the left ventricle and the aorta, controlling blood flow from the heart to the body. The mitral valve, on the other hand, is situated between the left atrium and left ventricle and consists of two cusps. Lastly, the pulmonary valve controls blood flow from the right ventricle into the pulmonary artery, directing deoxygenated blood towards the lungs. Each of these valves plays a crucial role in the heart's function, but only the tricuspid valve is associated with the right atrioventricular regulation.
