We can produce concentrated urine. This is facilitated by a special mechanism. Identify the mechanism.
Reabsorption from PCT
Reabsorption from collecting duct
Reabsorption/secretion in DCT
Counter current mechanism in Henle's loop/Vasa recta
MECHANISM OF CONCENTRATION OF THE FILTRATE -
Mammals have the ability to produce a concentrated urine. The Henle’ s loop and vasa recta play a significant role in this.
- wherein
The flow of filtrate in the two limbs of Henle’s loop is in opposite directions and thus forms a counter current.
Correct option is 4
