Vedclass · Answer

(A) The counter-current mechanism,involving the Loop of Henle and the vasa recta,creates an osmotic gradient in the renal medulla. As the isotonic glomerular filtrate passes through the descending limb of the Loop of Henle,water is reabsorbed,making the filtrate hypertonic. In the ascending limb,electrolytes are actively reabsorbed,making the filtrate hypotonic. However,the overall effect of the counter-current multiplier system in the presence of $ADH$ is to concentrate the filtrate,ultimately leading to the formation of hypertonic urine.

The counter-current multiplier system changes the isotonic glomerular filtrate into
