Detailed explanation-1: -The renal vein carries blood away from the heart and so carries the least amount of urea formed in the blood.
Detailed explanation-2: -The main blood vessel that carries blood from the kidney and ureter to the inferior vena cava (a large vein that carries blood to the heart from the lower part of the body).
Detailed explanation-3: -The renal vein takes purified blood away from the kidney to reach the inferior vena cava. There are two renal veins in the human body. The inferior vena cava is the largest vein that pours deoxygenated blood into the heart.
Detailed explanation-4: -The Renal Vein is the blood vessel with the lowest urea concentration. Because urea is excreted through the kidneys, the main artery that drains the blood, the renal vein, contains the lowest concentration of urea.
Detailed explanation-5: -Oxygenated blood comes to the kidneys from the right and left renal arteries off the abdominal aorta. Deoxygenated blood leaves the kidneys via the right and left renal veins that run into to the inferior vena cava.
