Question

Atrioventricular valves (AV) - Location - 2 kinds:

a) Located between atria and ventricles; Types: Bicuspid (mitral) and tricuspid
b) Located between ventricles and arteries; Types: Pulmonary and aortic
c) Located between atria and arteries; Types: Semilunar and atrioventricular
d) Located between veins and arteries; Types: Left and right

Answer 1

Atrioventricular valves are one-way valves located between the atria and ventricles in the heart. There are two types of AV valves: bicuspid (mitral) valve and tricuspid valve. The pulmonary and aortic valves are not AV valves; they are semilunar valves located between the ventricles and arteries.

Step-by-step explanation:

Atrioventricular valves, also known as AV valves, are one-way valves located between the atria and ventricles in the heart. There are two types of AV valves: the bicuspid (mitral) valve, located between the left atrium and ventricle, and the tricuspid valve, located between the right atrium and ventricle.

The pulmonary and aortic valves are not AV valves; they are actually semilunar valves located between the ventricles and arteries. Semilunar valves are shaped like half-moons.

The valves located between veins and arteries are not AV valves either. There are no AV valves located between the atria and arteries.
