the pressurized superhighway your blood takes when it's running away from your heart.
means A large blood vessel that carries oxygenated blood away from the heart to the rest of the body.
from From the Greek 'artēria.' Here's the twist: the ancient Greeks thought arteries carried air, not blood — because in a corpse the arteries empty out and look hollow. So the name likely ties to 'aēr' (air), the same root behind 'air' itself; some link it to 'airein,' to lift or raise. The word reached English through Latin 'arteria.' We kept the name long after we learned it was full of blood, not breath.
