Anatomy of the Heart: Valves - ThoughtCo
Valves are flap-like structures that allow blood to flow in one direction. Heart valves are vital to the proper circulation of blood in the body. The heart has two kinds of valves, atrioventricular and semilunar valves. These valves open and close during the cardiac cycle to direct the flow of blood through the heart chambers and out to the rest of the body.
