Ques. 1AIPMT 2000
Concentration of urine depends upon which organ?
- Bowman's capsule
- Length of Henle's loop
- PCT
- Network of capillaries arising from glomerulus
Answer
(2) Length of Henle's loop
Solution
As per NCERT, the Henle's loop and vasa recta play a significant role in producing concentrated urine through the counter current mechanism.
⇒ This maintains an increasing osmolarity towards the inner medullary interstitium; a longer loop of Henle builds a steeper gradient, so more concentrated urine is formed.
