Verified step by step guidance

Understand the function of the pulmonary artery and pulmonary vein. The pulmonary artery carries deoxygenated blood from the heart to the lungs, while the pulmonary vein carries oxygenated blood from the lungs back to the heart.

Recall the pathway of blood circulation. Blood is oxygenated in the lungs and then transported back to the heart via the pulmonary vein.

Consider the oxygen content in different blood vessels. The pulmonary vein, having just received oxygenated blood from the lungs, contains the highest amount of oxygen.

Compare the oxygen levels in the pulmonary vein with other vessels listed. The inferior and superior vena cava carry deoxygenated blood from the body back to the heart, thus having lower oxygen levels compared to the pulmonary vein.

Conclude that the pulmonary vein contains the greatest amount of oxygen among the listed blood vessels, as it directly transports oxygen-rich blood from the lungs to the heart.
