Superior vena cava (A): Carries deoxygenated blood from the upper part of the body to the right atrium of the heart.
Inferior vena cava (B): Carries deoxygenated blood from the lower part of the body to the right atrium of the heart.
Pulmonary artery (C): Carries deoxygenated blood from the right ventricle of the heart to the lungs.
Pulmonary vein (D): Carries oxygenated blood from the lungs back to the left atrium of the heart.
Therefore, the pulmonary vein is the vessel that carries oxygenated blood.
