The ascending limb of the loop of henle
WebAbstract: The thick ascending limb (TAL) of Henle’s loop is a crucial segment for many tasks of the nephron. Indeed, the TAL is not only a mainstay for reabsorption of sodium (Na + ), potassium (K + ), and divalent cations such as calcium (Ca 2+) and magnesium (Mg 2+) from the luminal fluid, but also has an important role in urine ... WebCh 25 In the ascending limb of the loop of Henle the _____. A) thick segment moves ions out into interstitial spaces for reabsorption B) thick segment is permeable to water C) thin segment is not permeable to sodium and chloride D) …

Administration … WebJan 16, 2024 · The ascending limb is structurally divisible into two regions: a thin segment, nearest the tip of the loop, and a thick segment of varying lengths, which carries the filtrate outward into the cortex and into the distal convoluted tubule. It is currently believed that only the cells of the thick segments of the ascending limb are capable of ...
WebJan 17, 2024 · The Loop of Henle. The loop of Henle is a U-shaped tube that consists of a descending limb and ascending limb. It transfers fluid from the proximal to the distal tubule. The descending limb is highly permeable to water but completely impermeable to ions, causing a large amount of water to be reabsorbed, which increases fluid osmolarity to …
WebIn the loop of Henle, the permeability of the membrane changes. The descending limb is permeable to water, not solutes; the opposite is true for the ascending limb. Additionally, the loop of Henle invades the renal medulla, which is naturally high in salt concentration and tends to absorb water from the renal tubule and concentrate the filtrate.
