Final answer:
The tubular epithelial cells of the collecting duct and distal tubule have receptors for the 1) antidiuretic hormone (ADH), which plays a key role in stimulating water reabsorption to maintain fluid balance.
Step-by-step explanation:
The tubular epithelial cells of the collecting duct and distal tubule contain receptors for antidiuretic hormone (ADH), which stimulates water reabsorption. ADH, also known as vasopressin, promotes water recovery by increasing the permeability of the collecting ducts to water. It triggers the insertion of aquaporin water channels into the cell membranes, allowing water molecules to be reabsorbed from the urine back into the bloodstream through osmosis. This process is crucial for maintaining fluid balance and concentration of urine.
