Detailed explanation-1: -The valves help ensure that blood flows at the right time and in the correct direction. The tricuspid valve ensures that blood flows from the right atrium to the right ventricle. It also prevents blood from flowing backward between those two chambers.
Detailed explanation-2: -It prevents the blood from flowing back from the aorta into the heart when the pumping chamber relaxes. BAV is present at birth (congenital).
Detailed explanation-3: -Two of the valves, the mitral and the tricuspid valves, move blood from the upper chambers of the heart (the atria) to the lower chambers of the heart (the ventricles). The other two valves, the aortic and pulmonary valves, move blood to the lungs and the rest of the body through the ventricles.
