Vedclass · Answer

(A) The loop of Henle is a crucial part of the nephron involved in the concentration of urine.The descending limb of the loop of Henle is permeable to water but almost impermeable to electrolytes.This allows water to move out of the filtrate into the interstitial fluid due to the high osmolarity of the medullary interstitium,thereby concentrating the filtrate.Conversely,the ascending limb is impermeable to water but allows the transport of electrolytes.

Column-$I$	Column-$II$
$a. PCT$	$i. \text{Selective secretion of } H^+ \text{ and } K^+ \text{ ions}$
$b. DCT$	$ii. 70-80\% \text{ of electrolytes and water reabsorption}$
$c. \text{Descending limb}$	$iii. \text{Allows passage of small amounts of urea}$
$d. \text{Ascending limb}$	$iv. \text{Permeable to water}$
$e. \text{Collecting duct}$	$v. \text{Permeable to salts}$

The descending limb of the loop of Henle is ..........
