WebThe thick ascending limb is often called the diluting segment. It is water impermeable but reabsorbs considerable amounts of salt, resulting in the separation of salt from water. The salt is trapped in the medulla, whereas the water is carried away into the cortex, where it may return into the systemic circulation. Web6 dec. 2016 · The medullary thick ascending limb of Henle’s loop (mTAL) is crucial for urine-concentrating ability of the kidney. It is water tight and able to dilute the luminal fluid by active transcellular NaCl transport, fueling the counter current mechanism by increasing interstitial osmolality. While chloride is exclusively transported transcellularly, approx. … halimbawa ng synthesis for the literature

Web7 apr. 2024 · Here, the sodium chloride is transported from a thick portion of the ascending limb without accompanying water so that an osmotic gradient of approximately 200 mm/kg is generated. The active sodium transport is accomplished by Na + , K + -ATPase which are located in the basolateral membranes of the tubular cells. WebWhile it has been generally accepted that active NaCl transport in the thick ascending limb of Henle's loop plays the most fundamental role in the operation of the countercurrent multiplication system in the renal medulla, it is still a matter of considerable dispute whether the thin ascending limb (tAL) also has an active salt transport system …
