Detailed explanation-1: -The valves open and close to help blood move along its path: Blood that needs oxygen flows from your body into the right atrium. It then flows through the tricuspid valve to the right ventricle. The right ventricle pumps the blood through the pulmonary valve and into your lungs, where it picks up oxygen.

Detailed explanation-2: -The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle. Normal valves have 3 flaps (leaflets), except the mitral valve.

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.

Detailed explanation-4: -The valves open and shut in time with the pumping action of your heart’s chambers. The opening and closing involve a set of flaps called cusps or leaflets. The cusps open to allow blood to flow out of a chamber and close to allow the chamber to refill with blood.
