Statement-1: Small amount of urea enters the thick segment of Henle's loop which is tranported back to interstitium by collecting tubules.
Statement-2: Collecting tubules and thick segment of Henle's loop are permeable to urea.

Segments of Henle's loop which is permeable and impermeable to water respectively

Both the thin and thick segments of the ascending limb of loop of Henle transport NaCl out to the interstitial fluid. What is difference in their respective mode of transport?

Read the following statements and select the correct option Statement 1 : When the urine moves through the descending limb, it becomes hypertonic to blood plasma and as it passes through the ascending limb of Henl's loop it becomes hypotonic to blood plasma Statement : The decending limb is permeable to sodium ions, while the ascending limb is impermeable to sodium ions
