Explanation:
Detailed explanation-1: -Chloride reabsorption at the loop of Henle was 0.72 (normal values 0.66-0.90), minimal urine osmolality 71 mosm/kg (normal values less than 75 mosm/kg) and chloride fractional clearance 0.44 (normal values 0.3-6.8). An impaired chloride reabsorption at the loop of Henle was found 6 months later.
Detailed explanation-2: -The thick ascending limbs are composed of cuboidal cells, but unlike the proximal convoluted tubule, they do not have apical brush borders.
Detailed explanation-3: -Henle’s loop consists of the straight portion of the proximal tubule, the thin descending and (in long loops) thin ascending limbs, and the thick ascending limb (Fig. 1.13; see also Fig. 1.2).
