Etymology
Origin of artery
First recorded in 1350–1400; Middle English, from Latin artēria, from Greek artēría “windpipe, trachea, artery”; see aorta
Explanation
An artery is a major blood vessel that carries blood away from your heart. For a healthy heart, keep your arteries clean! The word artery comes from the Greek arteria, which means "windpipe." In ancient times, an artery was thought to be a kind of air duct, because after someone dies, their arteries are empty of blood. Today we know that arteries (and veins) perform a vital job, constantly moving blood around our bodies. Systems of rivers or roads with networks and branches that resemble the human circulatory system can also be called arteries.
