The loop of Henle, specifically the descending limb, is responsible for establishing the vertical osmotic gradient in the medulla of the kidney. As filtrate flows down the descending limb, water leaves the tubule and enters the hyperosmotic interstitium, which becomes increasingly hypertonic as it descends deeper into the medulla. This creates the gradient necessary for the reabsorption of water by the collecting ducts.
