Question

Urine is concentrated to its maximum in loop of Henle in

• A. Descending limb
• B. Thick asccending limb
• C. Hair-pin bend between descending and ascending limbs
• D. Area between ascending limb and distal convoluted tubule

Answer 1

Answer: (D)

Area between ascending limb and distal convoluted tubule

• When there is a water deficit in the body, the kidney forms concentrated urine by continuing to excrete solutes while increasing water reabsorption and decreasing the volume of urine formed.
• The part of the nephron helps in forming concentrated urine is Capillary beds surrounding the loop of Henle, the proximal and distal convoluted tubules. As the filtrate flows through the nephron, elements of the blood get added to or removed from the nephron.
• Hence, Urine is concentrated to its maximum in the loop of Henle in Area between ascending limb and distal convoluted tubule.
• So, the correct answer is 'Area between ascending limb and distal convoluted tubule'.
