Who coined the term artery?

Answer 1

The heart's muscle, like any other muscle, would require its own supply of oxygen and nourishment. Its own quota for self is obtained through an exclusive set of arterial channels which originate from the mouth of the aorta. These special tubes travel the surface of heart as if embracing it. These are shaped like a "corona" (crown), hence the name coronary arteries. The term was coined by Galen, the great Roman anatomist and physician, in the second century A.D. The pencil-sized coronary arteries originate from the principle arterial trunk known as aorta.

The ancient Greeks first used the term artery. It means "air pipe" as they thought that was what went through them. Galen later used the same term.
