Explanation about the establishment of an osmotic gradient in the renal medulla.
Introduction:
In the kidney, Henle’s Loop is part of the nephron where reabsorption takes place. It consists of two portions namely proximal convoluted tubule and distal convoluted tubule. Its main function is to create a concentration gradient in the medulla of the kidney, especially a high urea concentration. It uses electrolyte pumps near the papillary duct in collecting duct system. The water present in the filtrate flows through the channel out of the duct reducing the concentration gradient. This process triggers for water reabsorption.
