WebIn the thick ascending limb of the loop of Henle, NaCl reabsorption is mediated by a Na+/2Cl-/K+ cotransport system, present in the luminal membrane of this nephron segment. Loop diuretics such as furosemide (frusemide), piretanide, bumetanide and torasemide bind reversibly to this carrier protein, thus reducing or abolishing NaCl reabsorption. WebBriefly explain the processes of filtration and reabsorption in an excretory tubules, as to whether: (a) transport is selective or non-selective; (b) materials are entering the tubules or moving into the blood in nearby capillaries.

WebOct 25, 2024 · The nephron loop is the U-shaped bend of a nephron which extends through the medulla of the kidney. Histologically, it consists of two parts; thin descending and thin ascending limbs. Both limbs are composed of simple squamous epithelium. The cells have few organelles, little to no microvilli and low secretion abilities. WebWater and urea are permeable in the descending loop of henle. Impermeable: Na+, Cl-. Water will move from the wall of the lumen and into the interstitial because of high solute concentration in the interstitial. Virtually there will be about the same amount of solute in the tubular lumen and interstitial. Therefore, the solutes in the tubular ... WebThey knew that the loop of Henle was involved in concentrating the urine somehow but so far as they could tell, all it did was dilute it. The answer is in the collecting ducts. After going through the distal tubule, the urine passes into the collecting ducts. The collecting ducts travel through the medulla on their way out of the kidney. trent barton the keyworth

WebJul 5, 2012 · The aims of the loop of henle is to reduce the volume of water and solutes within the urine but without changing the concentration. In doing this it creates a hypertonic medulla. It does this by using a countercurrent multiplier. This is maintained by the vasa recta. This hypertonic medulla not only helps reabsorb water from the loop of henle ... WebLoop of Henle or nephron loop in the kidney is a tubule that opens from the proximal convoluted tubule (PCT) and leads to the distal convoluted tubule. Its vital role is to produce a concentration gradient in the kidney and help in the filtration process. Its structure is composed of a thin descending loop and an ascending loop.
