Question

Which hormone is responsible for altering the permeability of the distal convoluted tubules to water and thus increasing water reabsorption?

Answer 1

The hormone is ANTIDURETIC HORMONE, ADH.
The collecting duct and the distal convoluted tubules vary in their permeability to water based on the quantity of ADH present. The collecting duct becomes more permeable to water when the ADH production increases. As the ADH production decrease, the urine volume increases. <span />
