Concentration of urine in organisms depends upon (a) Length of loop of Henle (b) PCT (c) DCT (d) Intake of water
Option A. The descending limb of Henle loop is permeable to water and impermeable to electrolytes. The longest loop of Henle occurs in kangaroo and rat. The long loop of Henle helps to minimize water loss and maximize reabsorption. Hence concentration of urine in the organism depends on the length of the loop of Henle.
