(b) length of Henle’s loop

(c) P.C.T.

(d) network of capillaries arising from glomerulus.

Answer 1

ANS: B

The length of Henle's loop

The concentration of urine depends on the length of Henle’s loop.

Becuase it is a hairpin-shaped structure present in the section of a kidney tubule situated between the proximal and distal tubules in the nephron. It has thin descending limb which is involved in the permeability of water and the other one ascending limb which is impermeable to water and other ions and water across the walls of the loop function as a countercurrent multiplier in association with vasa recta resulting in the production of concentrated urine in the collecting duct.
