Medullary loop
WebNH4+ absorption by the medullary thick ascending limb (MTAL) of Henle's loop, which causes the accumulation of NH4+/NH3 in the medullary interstitium, is a key step in the renal handling of ammonia. Accumulation of NH4+/NH3 in the medullary interstitium is necessary to the secretion of ammonia in the medullary collecting ducts and then to …
