Detailed explanation-1: -Blood passes through a valve before leaving each chamber of the heart. 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.
Detailed explanation-2: -Heart valves control the flow of blood so that it moves in the right direction. The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle.
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: -Tricuspid valve. Located between the right atrium and the right ventricle. Pulmonary valve. Located between the right ventricle and the pulmonary artery. Mitral valve. Located between the left atrium and the left ventricle. Aortic valve. Located between the left ventricle and the aorta.
