What is the role of Henle's loop and vasa recta in the renal system?
What is the role of Henle's loop and vasa recta in the renal system?
To transport NaCl
To transport urea
To maintain a concentration gradient in the medullary interstitium
To produce a dilute urine
Solution
The proximity between the Henle's loop and vasa recta, as well as the counter current in them help in maintaining an increasing osmolarity towards the inner medullary interstitium, which helps in maintaining a concentration gradient in the medullary interstitium.
