Concentration of urine depends upon which organ?
A
Bowman's capsule
B
length of Henle's loop
C
P.C.T.
D
network of capillaries arising from glomerulus.
Answer
length of Henle's loop
Explanation
Solution
Concentration of urine depends upon the length of Henle's loop. Loop of Henle is the hairpin shaped section of a kidney tubule situated between the proximal and distal tubules in the nephron. It consists of a thin descending limb which is permeable to water and a thick ascending limb which is impermeable to water complex movements of ions and water across the walls of the loop enable it to function as a countercurrent multiplier, resulting in the production of concentrated urine in the collecting duct.
