Heart valve

A heart valve is a one-way valve that normally allows blood to flow in only one direction through the heart. The four valves are commonly represented in a mammalian heart that determines the pathway of blood flow through the heart. A heart valve opens or closes incumbent on differential blood pressure on each side. The four valves in the mammalian heart are: The mitral valve and the aortic valve are in the left heart; the tricuspid valve and the pulmonary valve are in the right heart. The heart also has a coronary sinus valve, and an inferior vena cava valve, not discussed here.
