Physiology.
| Substance | Permeability |
|---|---|
| urea | Moderate permeability. |
| water | Highly permeable. Water is readily reabsorbed from the descending limb by osmosis. |
Furthermore, what does the descending loop of Henle absorb?
The descending loop of Henle receives isotonic (300 mOsm/L) fluid from the proximal convoluted tubule (PCT). The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are not readily reabsorbed.
One may also ask, why is the descending loop of Henle thinner than the ascending loop of Henle? The thin descending loop is highly permeable to water (which is easily transferred to the interstitium) and less permeable to solutes. On the other hand, the thin ascending limb is highly permeable to sodium but impermeable to water.
Keeping this in view, what is the main function of the descending loop of Henle?
This part of the nephron is called the loop of Henle. Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.
What leaves the filtrate in the ascending loop of Henle?
Ascending Loop of Henle—Loop Diuretics Fluid entering the loop of Henle is isotonic (osmolarity 300 mOsm/L) but the volume is only a third of the volume originally filtered into Bowman's capsule. The descending limb of the loop of Henle is permeable to water. Water diffuses into the hyperosmolar medullary interstitium.
