The concentration of urea is lower in the renal vein than in the renal artery because Responses the kidneys add urea to the blood. the kidneys add urea to the blood. little reabsorption of urea occurs in the nephron. little reabsorption of urea occurs in the nephron. Bowman’s capsule removes water from the filtrate. Bowman’s capsule removes water from the filtrate. the peritubular capillary network passes urea to the loop of Henle.

Q1: As the filtrate moves down the collecting duct of the nephron, ______. A) no urea is reabsorbed because urea is a waste product that the body needs to get rid of. B) urea is actively transported into the filtrate to prevent it from accumulating in the renal medulla. C) some urea is reabsorbed from the filtrate in order to increase the osmolarity of the renal medulla. Q8: When antidiuretic hormone (ADH) levels are low, this causes ________. A) less of the water reaching the collecting ducts to be reabsorbed. B) more aquaporins to be activated to increase the reabsorption of water. C) vasodilation of the efferent arteriole to increase the glomerular filtration rate. D) the urine to have a very high concentration of ions and nitrogenous wastes.
