The flow of blood through the heart is controlled by four�valves: thetricuspid,�pulmonary semilunar,�mitral, and�aortic semilunar valves. The�tricuspid valve�controls the opening between the right atrium and the right ventricle. The�pulmonary semilunar valve�is located between the...

Inside the heart, four valves open and close in precise sequence to keep the blood moving in the appropriate direction. Two of the heart's valves control the flow of blood from the upper chambers of the heart, or atria, to the lower chambers, or ventricles. Two other valves control the...
