In brief: Think swinging gate

The aortic valve is like a gate situated at the exit of the heart, that needs to swing open every time blood is ejected from the heart, and then needs to shut tight after ejection, preventing backflow of blood into the heart while it is relaxing.
It is comprised of 3 cusps, like the doors of a gate, which swing outward simultaneously, and then come back to swing shut.

In brief: Aortic valve

The valve opens to allow flow out of the heart to the body.
If it doesn't open properly we call this stenosis. It has to close properly to keep blood flowing in a forward direction. If it doesn't we call this insufficiency. Either or both abnormalities can exist in the valve.
