noun

aorta

ay-OR-tuh/eɪˈɔːrtə/

The main artery carrying blood from the heart to the body.

The model shows the aorta curving upward from the heart.

An isolated anatomical heart with its large aortic trunk clearly emphasized: it emerges from the left ventricle, arches above the heart with three superior branches, and continues downward as the descending aorta.
Etymology

Greek aortē meant a strap for hanging something and was applied by Aristotle to the heart’s great artery. The anatomical term preserves that older image of something hung up.
