Medical Definition of Aortic valve

Aortic valve: One of the four valves in the heart, this valve is situated at exit of the left ventricle of the heart where the aorta (the largest of all arteries) begins.

The aortic valve lets blood from the left ventricle be pumped up (ejected) into the aorta but prevents blood once it is in the aorta from returning to the heart.
