The word corona is a Latin word meaning “crown”, from the Ancient Greek κορώνη (korōnè, “garland, wreath”). It was applied to the coronary arteries because of a notional resemblance (compare the photos).
The word arterie in Anglo-French (artaire in Old French, and artērium in Latin) means “windpipe” and “an artery.” It was applied to the coronary arteries because the arteries do not contain blood after death.
