<prompt> Diluting segment of a nephron is:Descending limb of loop of HenleThick ascending limb of loop of HenleDCTCollecting duct  <response>: Thick ascending LOH is ka the diluting segments of the nephron. It is impermeable to water. It has NKCC cotranspoer proteins that reabsorb Na, K, 2Cl- ions. Thus,There is a net reabsorption of solutes with no movement of water, making the tubular fluid that reaches the DCT hypotonic.
