Show Answer
Answer:
Correct Answer: C
Solution:
- In mammals, the blood vessel that would normally carry the largest amount of urea is the hepatic vein.
The liver is the primary site for the conversion of ammonia, a toxic byproduct of protein metabolism, into urea through the urea cycle. Once urea is produced in the liver, it is released into the bloodstream. The hepatic vein carries blood away from the liver and thus would have the highest concentration of urea immediately after it is produced.
