Systemic Arteries carry oxygen rich blood (also called oxygenated blood). Pulmonary Arteries carry oxygen poor (deoxygenated) blood
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
Oxygen All arteries, except the pulmonary and umbilical arteries, carry oxygen. None of them carry carbon dioxide.
The arteries of the pulmonary circulation are unusual. They carry oxygen-poor blood, unlike the systemic arteries.
