The main function of the nephron loop is to create a concentration gradient in the renal medulla, which allows for the formation of either a large volume of very dilute urine or a small volume of very concentrated urine, depending on the body's needs. This is achieved through active transport of salts out of the ascending limb and passive reabsorption of water in the descending limb.
