Plural of coronary; arteries or veins that supply blood to the heart muscle, or adjective referring to the heart's blood supply.
From Medieval Latin coronarius (relating to a crown), from corona, because these arteries encircle the heart like a crown.
Heart disease caused by blocked coronary arteries is the leading cause of death in developed nations—yet knowing that these vessels are literally named for their crown-shaped pattern around your heart is oddly poetic!
