Answer 2

Answer:

The hepatic vein has the highest concentration of urea.

Explanation:

Protein present in the food is broken down into amino acids. The excess amino acids are broken down by the liver producing urea. Hence, liver has a high concentration of urea.

This urea is then carried out of the liver by the hepatic vein that is responsible for carrying deoxygenated blood from the liver to the inferior vena cava of the heart.
