The heart has four valves that regulate blood flow through the heart. The mitral valve and the tricuspid valve (atrioventricular valves) are located between the atria and ventricles. The aortic valve and pulmonary valve (semilunar valves) are located between the ventricles and the arteries that emerge from the heart.
