Which of these is found in larger quantities in the renal artery than in the renal vein.
A
glucose
B
urea
C
water
D
oxygen
E
carbon dioxide
Explanation: 

Detailed explanation-1: -Glucose is transported by the blood to all the parts. Thus, the renal artery contains more glucose than the renal vein.

Detailed explanation-2: -Deposits of fat and cholesterol (plaque) can build up in the renal arteries. These plaque deposits can lead to atherosclerosis (narrowed arteries) and renal artery stenosis (blockages). Blood flows more slowly through narrowed renal arteries. As a result, pressure builds up in blood vessels throughout the body.

Detailed explanation-3: -Renal Veins carry filtered blood from the kidneys to the posterior vena cava. Renal Arteries carry unfiltered blood from the aorta to the kidneys.

Detailed explanation-4: -Answer and Explanation: The renal artery is thicker than the renal vein because D. arteries have more smooth muscle. Arteries have more smooth muscle because they are subjected to higher levels of blood pressure.

Detailed explanation-5: -Renal artery carries blood to the kidney whereas the renal vein carries blood away from the kidney. As the kidney filters the blood, renal vein which carries blood away has less urea concentration than the renal artery.
