Question

Atrioventricular (AV) valves:

a. Tricuspid: between RA and V
b. Bi/MITRAL= bTWN LA & V
c. Prevent the valves from everting

Answer 1

Atrioventricular (AV) valves are located between the atria and ventricles of the heart and prevent the backflow of blood. The tricuspid valve is between the right atrium and ventricle, and the mitral valve is between the left atrium and ventricle.

Step-by-step explanation:

Atrioventricular (AV) valves are one-way valves located between the atria and ventricles of the heart. The tricuspid valve is located between the right atrium and ventricle, while the mitral (or bicuspid) valve is located between the left atrium and ventricle.

These valves prevent the backflow of blood and ensure that it flows in the correct direction. The tricuspid valve has three flaps of tissue, while the mitral valve has two flaps.

If these valves were to evert, or open in the opposite direction, blood would flow back into the atria instead of being pumped into the ventricles and out to the rest of the body.
