Couldn't get your point. My point is whereas all the arteries carry oxygenated blood from the heart, and all the veins carry de-oxygenated blood to the heart, the pulmonary artery and the pulmonary vein do exactly opposite. What it means is that the pulmonary artery and the pulmonary vein do not conform to that definition. So they are exceptions.

You'll never encounter such a question on your paper. Rest assured.
