WebTo identify the mechanism of Cl{sup {minus}} transport across the thin ascending limb of Henle's loop (TAL), the authors examined effects of anion transport inhibitors and ionic substitution in the isolated segments of hamsters using the in vitro microperfusion technique. 4,4{prime}-diisothiocyanostilbene-2,2{prime}-disulfonic acid (DIDS) at 10{sup … The Loop of Henle has a hairpin configuration with a thin descending limb and both, a thin and thick ascending limb (TAL). The thin descending and ascending segments have thin, squamous epithelial membranes with minimal metabolic activity. The TAL has cuboidal epithelial membranes and is quite metabolically active. See more The descending limb is highly permeable to water, with reabsorption occurring passively via aquaporin-1 (AQP1) channels. Small amounts of urea, sodium (Na+) and other ions … See more The primary site of sodium reabsorption in the Loop of Henle is the thick ascending limb (TAL). The TAL is impermeable to water. Sodium reabsorption is active – the driver is the Na+/K+ … See more The thin ascending limb is impermeable to water, due to it having no aquaporin channels. Na+ reabsorption occurs passively through epithelial Na+ (eNaC) channels and Chloride … See more As the thick ascending limb is impermeable to water, the interstitium becomes concentrated with ions, increasing its osmolarity. This drives water reabsorption from the descending limb as water moves from … See more touchscreen chromebook with dual camera https://esfgi.com
