Reabsorption in which of the following segment is minimum?
1 PCT
2 Henle's loop
3 Collecting duct
4 DCT
Explanation:
(c) Since the loop of Henle reabsorbs water in the descending limb but is also impervious to water in the ascending limb, diluting the urine; So the net reabsorption is minimum.

$\text{N}{{\text{a}}^{+}}$and $\text{C}{{\text{l}}^{-}}$both are removed by
1 Ascending limb of Henle's loop
2 Proximal convoluted tubule
3 Both (a) and (b)
4 Descending limb of Henie's loop
Explanation:
(c) $\text{N}{{\text{a}}^{+}}$and $\text{C}{{\text{l}}^{-}}$both are removed by ascending limb of Henle's loop and proximal convoluted tubule.

Through the thick segment of ascending limb of Henle's loop the
1 $\text{NaCl}$ can pass by active transport from filtrate to the interstitial fluid.
2 $\text{NaCl}$ can pass by passive transport into interstitial fluid.
3 $\text{NaCl}$ cannot pass from the filtrate to interstitial fluid.
4 Water can pass freely from filtrate to interstitial fluid.
Explanation:
(a) The ascending limb of loop of Henle has a thin and a thick segment. The thin ascending limb is found in the medulla of the kidney, and the thick ascending limb can be divided into a part that is in the renal medulla and a part that is in the renal cortex. Through the thick segment of ascending limb of loop of Henle, the $\text{NaCl}$ can pass by active transport from the filtrate to the interstitial fluid. The medullary ascending limb remains impermeable to water. Sodium, potassium $\left( {{\text{K}}^{+}} \right)$and chloride $\left( \text{C}{{\text{l}}^{-}} \right)$ions are reabsorbed by active transport. ${{\text{K}}^{+}}$is passively transported along its concentration gradient through a ${{\text{K}}^{+}}$leak channel in the apical aspect of the cells, back into the lumen of the ascending limb.
