aortic orifice

Meaning

The opening between the left ventricle of the heart and the aorta, through which oxygenated blood is pumped to the rest of the body.

Examples

• The aortic orifice is guarded by the aortic valve, which prevents blood from flowing back into the heart.
• Narrowing of the aortic orifice can lead to a condition known as aortic stenosis.
