Differentiate between ascending limb and descending limb of loop of Henle.

Ascending Limb and Descending Limb of Henle's Loop

What difference is observed in the ascending and the decending limbs of Henle's loop regarding permeability to H_(2)O ?

Assertion A: The renal fluid becomes increasingly concentrated when it flows down in the descending limb of loop of Henle towards the inner medulla but its concentration decreases in the ascending limb when it flows towards the cortex Reason R: The descending limb of the loop of Henle reabsorbs water, the ascending limb is impermeable to water but salts are reabsorbed

The thin segment of descending limb of Loop of Henle is lined by

Assertion : While on going down the loop of Hece, the filtrate becomes hypotonic. Reason : The descending limb of loop of Henle is impermcable to both wster and electrolytes.

In descending limb of loop of Henle, filtrate becomes

Main function of descending loop of Henle is

Descending limb/Ascending limb of loop of Henle is impermeable to water.

Assertion : In the descending limb of loop of Henle , the urine is hypertonic , while in ascending limb of loop of Henle , the urine is Hypotonic . Reason : Descending limb is impermeable to Na' while ascending limb is impermeable to H_(2)O
