Pulmonary Artery


Updated December 18, 2006

Definition: Large blood vessel that carries blood away from the heart, towards the lungs, and supplies the large capillary network in lungs by which oxygen enters the blood.

The Pulmonary Artery is the only artery in the body that carries blood with low oxygen levels. Except for the Pulmonary Artery, all other arteries exclusively transport blood that contains high levels of oxygen.
