Question

Which of the following veins carries oxygenated blood?

• A. Superior vena cava
• B. Inferior vena cava
• C. Pulmonary vein
• D. Renal vein

Answer 1

The correct option is C

Pulmonary vein

Veins are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. Inferior vena cava carries deoxygenated blood from the lower half of the body to the right atrium of the heart. And the vein that carries deoxygenated blood from the upper half of the body is the superior vena cava. The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava.
