Explanation:
Detailed explanation-1: -A distal convoluted tubule connects to the collecting duct system that fine-tunes salt and water reabsorption and plays a major role in acid–base balance.
Detailed explanation-2: -Water excretion by the kidney is regulated by the peptide hormone vasopressin. Vasopressin increases the water permeability of the renal collecting duct cells, allowing more water to be reabsorbed from collecting duct urine to blood.
