Explanation:
Detailed explanation-1: -The main role of the collecting duct is the reabsorption of water, through the action of anti-diuretic hormone (ADH) and aquaporins. ADH is produced in the hypothalamus, and stored in the posterior pituitary gland until it is released.
Detailed explanation-2: -As more sodium is reabsorbed by the cell, even more water travels into the interstitium. At times of extreme dehydration, the collecting duct can absorb about 20% of the total amount of water found in the filtrate from the collecting duct.
