Aortic valve

Location of aortic valve in heart and detail of open and closed valve

The aortic valve has three flaps that work like a one-way gate. When the heart pumps, the aortic valve opens to allow oxygen-rich blood to flow from the left ventricle into the aorta. When the heart rests between beats, the aortic valve closes to keep blood from flowing backward into the heart.
