Pulmonary arteries are blood vessels which carries de-oxygenated blood from the right ventricle of the heart to the lungs.
A blockage of the artery by a clot, plaque or fat such that blood is not allowed to flow to the lungs is a pulmonary embolism, a life threatening condition. The pulmonary artery does not supply the lungs with nutrition. That function is served by the bronchial arteries, which branch off from the aorta.
