    The Aortic Valve
    The aortic valve opens to allow blood to flow into the aorta and then closes to prevent blood from flowing back into the heart. This animation shows the aortic valve in action.


  • The heart’s aortic valve:

    • Closes off the lower right chamber that holds the oxygen-rich blood before it is pumped out to the body
    • Opens to allow blood to leave the heart (from the left ventricle to the aorta and on to the body)
