The loops of Henle establish a concentration gradient in the medulla of the kidney by using a countercurrent mechanism. This involves the flow of fluid in opposite directions in the ascending and descending limbs of the loop, which creates a gradient of salt concentration in the interstitial fluid of the medulla. This gradient provides the driving force for the reabsorption of water from the collecting ducts, which helps to conserve water and concentrate the urine. Thus, the loops of Henle function as a countercurrent multiplier.
