Q. The largest vein is:

A
Inferior vena cava
B
Femoral vein
C
Axillary vein
D
Subclavian vein
Solution:
  • The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart.
  • The inferior vena cava (or caudal vena cava in some animals) travels up alongside the abdominal aorta with blood from the lower part of the body.
  • The superior vena cava (or cranial vena cava in animals) is above the heart, and forms from a convergence of the left and right brachiocephalic veins, which contain blood from the head and the arms.
