WebNov 29, 2006 · The function of this nephron segment is mainly tjo allow simple diffusion of substances through its walls. About 20% of the filtered water is reabsorbed in the descending limb, because, the ascending limb (both thin and thick parts) are impermeable to water – a characteristic which is important for concentrating urine. WebAs already indicated, the loop of Henle is critical to the ability of the kidney to concentrate urine. The high concentration of salt in the medullary fluid is believed to be achieved in the loop by a process known as countercurrent exchange multiplication. The principle of this process is analogous to the physical principle applied in the conduction of hot exhaust …
