Question

Vein having the highest concentration of urea is?

Answer 1

Hepatic vein:

1. The hepatic vein is the vein with the highest concentration of urea.
2. These veins carry deoxygenated blood from the liver to the inferior vena cava.
3. In the liver, urea is synthesized so since the hepatic vein originates from the liver and carries the deoxygenated blood to the inferior vena cava, it is rich in urea.
4. Thus, the hepatic vein is rich in urea.
