339722 Out of the four parts given below, which parts play significant role in forming concentrated urine in human?

339723 Medullary gradient is mainly developed due to

339724 Assertion :
Urine is hypertonic in the descending limb of loop of Henle, while urine is hypotonic in the ascending limb.
Reason :
Ascending limb is impermeable to \(\mathrm{Na}^{+}\)whereas the descending limb is impermeable to \(\mathrm{H}_{2} \mathrm{O}\).

339725 Which factor helps in maintaining an increasing osmolarity towards the inner medullary interstitium?
i. Counter current pattern in vasa recta
ii. Counter current pattern in Henle's loop
iii. Proximity between the Henle's loop and vasa recta
