Arteries and veins aren’t necessarily classified by what quality of blood they are carrying but by their direction of flow. Arteries run from the heart and veins run towards. In fact the pulmonary artery is dedicated to oxygen poor blood. It’s the vessel that carries blood from your heart to your lungs to diffuse CO₂ for O₂. Then your pulmonary vein carries back oxygenated blood to your heart to then be distributed. The same is also true with the arteries and veins in the umbilical cord. The umbilical artery carries oxygen poor blood to the placenta, or away from the heart of the fetus, and the umbilical vein runs the oxygenated blood back to the fetus.

blood in veins is deoxygenated as its being taken back to the heart. blood in arteries are oxygenated as it is being taken around the body to take oxygen to the cells.
