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 the collecting duct descends through the medulla, the increasing osmolarity in the surrounding interstitial fluid drives water reabsorption.
