Descending Loop Of Henle Function
The descending limb of the loop of henle is permeable to water. Scheme of renal tubule and its vascular supply.

The loop has a sharp bend in the renal medulla going from descending to ascending thin limb.
Descending loop of henle function. Metabolomics may be key to identifying diabetes related kidney disease. This function allows production of urine that is far more concentrated than blood limiting the amount of water needed as intake for survival. In the thin descending limb water is very permeable and is reabsorbed due to the existing concentration gradient in the medulla.
The osmolarity can reach a maximum of 1200 mosm l at the tip of the medullary interstitium in antidiuresis. More specifically the descending limb is highly permeable to water less permeable to solutes while the ascending limb is the opposite. Descending limb of loop of henle.
The concentration of tubular fluid is thus increased and its volume is decreased as it descends toward the tips of the loops. The ascending limb where loop diuretics work is impermeable to water. Some authors consider the nephron loop to be synonymous with the loop of henle while other authors include the proximal straight tubule nephron loop and distal straight tubule in this term.
Labeled at center left within the nephron of the kidney the descending limb of loop of henle is the portion of the renal tubule constituting the first part of the loop of henle. Thin descending limb of loop of henle the thin descending limb has low permeability to ions and urea while being highly permeable to water. The fluid entering the descending limb contains sodium chloride and other salts urea and other.
The fluid entering the descending limb contains sodium chloride and other salts urea and other chemicals that have been filtered out from the blood. The loop of henle has a thin descending limb a thick ascending limb and a thin ascending limb. Loop of henle long u shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles birds and mammals.
The loop of henle has a thin descending limb a thick ascending limb and a thin ascending limb. The loop of henle serves to create a concentration gradient throughout the nephron which helps increase the reabsorption of water and certain ions. Since the surrounding interstitial fluid is hypertonic to the filtrate in the descending limb water is drawn out of the descending limb by osmosis and enters blood capillaries.
Thin ascending limb of loop of henle. The principal function of the loop of henle is in the recovery of water and sodium chloride from urine. Water diffuses into the hyperosmolar medullary interstitium.
