Question

Which among the following is the largest vein in human body?

• A. Renal vein
• B. Pulmonary vein
• C. Superior Vena cava
• D. Aorta

Answer 1

The correct option is C Superior Vena cava

The venae cavae are large veins (venous trunks) that return deoxygenated blood from the body into the heart. In humans, they are called the superior vena cava and the inferior vena cava, and both empty into the right atrium. The superior vena cava is the largest vein which returns blood to the heart from the head, neck and both upper limbs.

The inferior vena cava returns blood to the heart from the lower part of the body.

So the correct option is C
