Increased Decreased Unchanged Qu 1 / 1 pts estion 3 Which of the following statements is incorrect? The thick ascending limb of Henle’s loop reabsorbs less urea than the inner medullary collecting tubule during antidiuresis. Urea concentration in the interstitial fluid of the renal medulla is greater than in the interstitial fluid of the renal cortex during antidiuresis. Urea reabsorption in the inner medullary collecting tubule is greater than in the distal convoluted tubule during antidiuresis. Urea reabsorption in the proximal tubule is normally less than in the medullary collecting ducts during antidiuresis.
