Reabsorption of required salts occurs in which part of nephron
|
|
Proximal convoluted tubule
|
|
|
Descending limb of the Loop of Henle
|
|
|
Ascending limb of the Loop of Henle
|
|
|
Distal convoluted tubule
|
Explanation:
Detailed explanation-1: -The thick ascending limb of Henle’s loop actively reabsorbs sodium chloride (NaCl) but is impermeable to water. Therefore this segment raises the osmolality of the interstitial fluid, thus generating medullary interstitial hypertonicity and a lumen-to-interstitium osmotic gradient.
Detailed explanation-2: -The thin ascending limb is impermeable to water, but it is permeable to ions. Sodium (Na+), potassium (K+) and chloride (Cl−) ions are reabsorbed from the urine by secondary active transport by a Na-K-Cl cotransporter (NKCC2).
Detailed explanation-3: -Thick ascending limbs of Henle’s loop have at least three major roles: (1) They reabsorb sodium chloride which dilutes the urine.
