Web6 apr. 2024 · The medullary interstitium is a tissue that surrounds the medulla's Henle loop. It aids renal water absorption by increasing hypertonicity, which pulls water out of the loop's thin descending limb of Henle and the collecting duct system. In turn, hypertonicity is created by an urea efflux from the inner medullary collecting duct.
