Counter current mechanism, all are true except
Countercurrent mechanism, a system in the renal medulla that facilitates concentration of the urine as it passes through the renal tubules, were medullary osmolarity created by urea.Ref: Ganong&;s review of medical physiology; 24th edition; page no; 687
Occurs due to opp flow in vasa recta and loop of henle
Seen in medullary nephron
Helps in creating osmolarity gradient
Urea has no role
