   The Heart Valves

 Four valves regulate blood flow through the heart.

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.
