Explanation:
Detailed explanation-1: -This part of the nephron is called the loop of Henle. Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.
Detailed explanation-2: -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.
