**Step-by-Step Solution:** 1. **Understanding the Structure of the Loop of Henle:** - The Loop of Henle consists of two main parts: the descending limb and the ascending limb. Each limb has different permeabilities to water and solutes. 2. **Concentration in the Descending Limb:** - The descending limb of the Loop of Henle has thin walls that are permeable to water but not to solutes. - As the glomerular filtrate moves down the descending limb, it encounters an increasing osmolarity in the surrounding medullary interstitium (the tissue surrounding the nephron). ...

Read the following statements and find out the INCORRECT statement . (a) During urine formation, the tubular cells secrete substance like H^+, Na^+ and HCO_3^- into the filtrate. (b) As glomerular filtrate move down in descending limb of Henle it gets concentrated and as concentrated filtrate pass upward in ascending limb of HL it gets diluted. (c) Conditional reabsorption of Na^+ and water takes place in PCT. (d) Reabsorption in ascending limb of HL is minimum.

Assertion: In terrestrial animals,counter current mechanism helps in the concentration of the filtrate to pass out concentrated urine. Reason: Descending limb is impermeable to water while ascending limb is impermeable to Na^(+)
