Maximum absorption of NaC1 in proximal convoluted tubule occurs due to the effect of: March 2009: (A) ADH, (B) Aldosterone, (C) Atrial natriuretic peptide, (D) Angiotensin II
Answer is D. Ans. D: Angiotensin II Angiotensin II acts at the PCT,Thick ascending loop of Henle/distal tubule, collecting tubule and leads to increased absorption of NaC1 and water and increased H+ secretion. ADH, Aldosterone and ANP acts at the collecting tubule and duct
