<prompt> Active resorption of sodium ion occurs in: March 2008Ascending loop of henleEarly distal tubuleProximal tubuleAll of the above  <response>: Ans. D: All of the above About 65 of the filtered electrolytes are absorbed in PCT actively Thin ascending loop of Henle: Passive diffusion of sodium Thick ascending loop of Henle: Active transpoation of sodium Early distal tubule: Similar propeies as that of thick ascending loop of Henle
