Where does the name pulmonary artery come from and named an artery if it is not oxiginated blood?

Whether they have oxygen or not, all arteries carry blood away from the heart. And, since the pulmonary arteries carry blood from the right ventricle of the heart to the lungs, it is appropriately called an artery. Any blood vessel that carries blood toward the heart is called a vein. So that is why the oxygenated blood from the lungs uses the pulmonary veins to carry it to the left atrium of the heart.
