The loop of Henle plays a crucial role in producing concentrated or diluted urine depending on the body's needs. It accomplishes this by actively removing electrolytes from the filtrate while allowing water to passively diffuse out of the descending limb and into the surrounding tissues. The ascending limb then pumps out additional electrolytes, resulting in a concentration gradient that allows for the reabsorption of more water in the collecting ducts. This process can lead to the formation of either a large volume of very dilute urine or a small volume of very concentrated urine.
