Heart Valves

Four valves regulate blood flow through your heart:

* The tricuspid valve regulates blood flow between the right atrium and right ventricle.

* The pulmonary valve controls blood flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen.

* The mitral valve lets oxygen-rich blood from your lungs pass from the left atrium into the left ventricle.

* The aortic valve opens the way for oxygen-rich blood to pass from the left ventricle into the aorta, your body's largest artery, where it is delivered to the rest of your body
