A common misconception is that all veins carry de-oxygenated blood and all arteries carry oxygen-rich blood. It is immaterial whether they carry oxygenated or deoxygenated blood. Arteries are the blood vessels carrying blood away from the heart whereas veins carry blood to the heart.
Pulmonary artery carries blood from heart to the lungs. This blood is deoxygenated, which has to be oxygenated in the lungs. Pulmonary vein carries blood from lungs to heart. This blood is oxygenated, which has to be be taken to the heart from where it is supplied to the rest of the body.
