Which of the following vessels carries oxygenated blood?

Rationale

The Pulmonary vein carries oxygenated blood.

The Pulmonary vein is the vessel that transports oxygen-rich blood from the lungs back to the heart, which then pumps the oxygenated blood to the rest of the body. This is an exception to the general rule that veins carry deoxygenated blood.

A (Pulmonary vein) CORRECT

The Pulmonary vein carries blood from the lungs to the left atrium of the heart. This is oxygenated blood, which is then distributed by the heart to the rest of the body. Therefore, the pulmonary vein is the correct answer to the question.

B (Superior vena cava) YOUR ANSWER

The Superior vena cava carries deoxygenated blood from the upper half of the body back to the heart. It does not carry oxygenated blood, so it is not the correct answer.

C (Pulmonary artery) YOUR ANSWER

Contrary to most arteries, the Pulmonary artery carries deoxygenated blood. It transports blood from the heart to the lungs, where it gets oxygenated. Therefore, the pulmonary artery is not the correct answer.

D (Inferior vena cava) YOUR ANSWER

The Inferior vena cava is the largest vein in the human body. It carries deoxygenated blood from the lower half of the body back to the heart. Thus, it does not carry oxygenated blood and is not the correct answer.

Conclusion

The Pulmonary vein is the correct answer because it carries oxygenated blood from the lungs back to the heart. The other options (Superior vena cava, Pulmonary artery, and Inferior vena cava) carry deoxygenated blood, either from the body to the heart or from the heart to the lungs. Therefore, they are not the correct answer to the question.

Which of the following vessels carries oxygenated blood?

The Pulmonary vein carries oxygenated blood.
