Which of the following is more concentrated in the blood within the renal artery than the blood within the
renal vein?
Answer Details
Urea is more concentrated in the blood within the renal artery than the blood within the renal vein. The renal artery carries blood from the heart to the kidneys, while the renal vein carries blood from the kidneys back to the heart. The kidneys filter waste products from the blood, and urea is one of the primary waste products of protein metabolism. As blood flows through the kidneys, urea is removed from the blood and excreted in the urine. Therefore, the blood within the renal vein has a lower concentration of urea compared to the blood within the renal artery, as the renal vein has already undergone filtration and removal of waste products.
