Simplified etymology

Aorta entered English in the mid-16th century and ultimately comes from Greek aeirein, “to raise.” Hippocrates used the term for branches of the windpipe, while Aristotle applied it to the great artery.

Via Late Latin aorta from Ancient Greek aorte, the name for the great artery arising from the heart. The Greek noun is related to aeirein, meaning to lift or raise. The figurative sense extends the anatomical image of a vital main channel.
