1.	Is the nephric filtrate present in which segment of the renal tubule is isotonic to plasma?(a) Collecting duct(b) Collecting tubule(c) PCT(d) DCTThis question was posed to me in my homework.My question is based upon Function of Tubules-1 topic in section Excretory Products and Elimination of Biology – Class 11
Answer» Correct option is (c) PCT Explanation: The NEPHRIC filtrate present in the PCT is isotonic to blood plasma i.e. 300 mOsmol/L. In PCT, there is obligatory reabsorption of WATER, i.e., ABSORPTION without the INFLUENCE of any HORMONE.
