(iii) The proximity between the Henle's loop and vasa recta, as well as the counter current in them increases osmolarity from cortex to medulla.
(iv) Osmolarity increasing from 300 mOsmol L' in the cortex to about 1200 mOsmol L' in the inner medulla.
(v) Osmolarity gradient from cortex to medulla is mainly caused by NaCl and urea.
(vi) Presence of osmolarity gradient helps in an easy passage of water from the collecting tubule thereby concentrating the filtrate (urine).
(vii) Human kidneys can produce urine nearly four times concentrated than the initial filtrate formed.
