The aorta (generally pronounced eɪˈɔːtə or "ay-orta") is the largest artery in the human body, originating from the left ventricle of the heart and bringing oxygenated blood to all parts of the body in the systemic circulation.

The course of the aorta

The aorta is usually divided into five segments/sections [1] [2] [3] [4]  :

Features

The aorta is an elastic artery, and as such is quite distensible. When the left ventricle contracts to force blood into the aorta, the aorta expands. This stretching gives the potential energy that will help maintain blood pressure during diastole, as during this time the aorta contracts passively.
