Solution & Step-by-step Explanation

Urea is synthesized in the liver via the Ornithine cycle. Therefore, the blood leaving the liver through the hepatic vein contains the highest concentration of urea. The renal vein carries blood away from the kidney after urea has been filtered out, so it contains the least amount of urea.
