Concentration of urine depends upon which organ?
Correct answer: B. Length of loop of Henle
- A. Bowman's capsule
- B. Length of loop of Henle
- C. PCT
- D. Network of capillaries arising from glomerulus
Explanation
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.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
