Question

Sixty to 70 percent of the water is reabsorbed in the Select one: - a. collecting duct b. renal corpuscle c. distal convoluted tubule d. proximal convoluted tubule ADH stimulates the reabsorption of water in Select one: a, only the distal convoluted tubule (DCT) o b. both the distal convoluted tubule and the collecting system c. only the collecting ducts d. the nephron loop What is the result of the countercurrent multiplication mechanism? Select one: a. decreased solute concentration in the descending limb of the nephron loop b. increased solute concentration in the descending limb of the nephron loop c. decreased transport of sodium and chloride in the ascending limb of the nephron loop d. osmotic flow of water from peritubular fluid into the descending limb of the nephron loop

Answer 1

28. Answer: Option D is correct
Explanation:
The proximal convoluted tubule is located in between Bowman's capsule and loop of Henle.
It contains abundant microvilli and absorbs 60%-70% of filtered water.

29. Answer: Option B is correct
Explanation:
ADH = Vasopressin
It is secreted by hypothalamus and stored in the posterior pituitary gland.
It stimulates the reabsorption of water in both the distal convoluted tubule and the collecting system.
