Aortic Orifice
The Aortic Orifice (pronounced: ay-or-tik or-uh-fis) is a medical term referring to the opening of the aorta, the main artery that carries blood away from your heart to the rest of your body.
Etymology
The term "Aortic Orifice" is derived from two words. "Aortic" comes from the Greek word "aortē", meaning 'the great artery', and "Orifice" is derived from the Latin word "orificium", meaning 'an opening or hole'.
Definition
The Aortic Orifice is the opening from the left ventricle of the heart into the aorta. It is the point of exit for oxygenated blood as it is pumped from the heart to be distributed throughout the body.
