Vedclass · Answer

(A) The counter-current mechanism is a process that helps in concentrating the urine. It primarily operates through the interaction between the $Henle's$ loop of juxtamedullary nephrons and the $vasa$ $recta$. The flow of filtrate in the two limbs of $Henle's$ loop is in opposite directions,and the flow of blood in the two limbs of the $vasa$ $recta$ is also in opposite directions. This arrangement facilitates the maintenance of an increasing osmolarity towards the inner medullary interstitium,which is essential for water reabsorption.
