Pulmonary Artery Blood: Oxygenated or Deoxygenated? - Heart & Circulation

The blood in the pulmonary artery is deoxygenated.

The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs. In the lungs, the blood is oxygenated and then returns to the heart via the pulmonary veins.
