Web4 Jul 2016 · In addition and importantly, ADH increases the permeability of the medullary portion of the collecting duct to urea. Finally, ADH stimulates reabsorption of NaCl by the thick ascending limb of Henle’s loop, the distal tubule, and the collecting duct. The actions of ADH on permeability of the collecting duct to water have been studied extensively. WebThe thin descending limb has low permeability to ions and urea, while being highly permeable to water. The loop has a sharp bend in the renal medulla going from descending to ascending thin limb. The thin ascending limb is impermeable to water, but it is permeable to ions. Proximal tubule and collecting duct are permeable to water.
