An artery is a blood vessel that carries blood away from the heart to the rest of the body. The word can also describe a main route or road that many people use.
From Latin “arteria,” from Greek “artēria,” originally used for windpipe and later for major blood vessels. Over time, it came to mean the large vessels carrying blood from the heart.
Arteries are the highways of your body, rushing life-carrying blood to every cell. Cities borrow the metaphor when they call big roads “arteries,” because blocking one can choke the whole system.
