WebBecause the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, … WebThe medullary interstitium is the tissue surrounding the loop of Henle in the renal medulla . It functions in renal water reabsorption by building up a high hypertonicity, which draws water out of the thin descending limb of the loop of Henle and the collecting duct system. This hypertonicity, in turn, is created by a an efflux of urea from the ...

It functions in renal water reabsorption by … WebSalt and urea are the major solutes in the renal medullary interstitium. Unfortunately, high salt (hypertonicity) causes DNA damage and cell death. In response, the renal medullary cells adapt to the hypertonicity by accumulating compatible osmolytes. A regulatory protein, tonicity-responsive enhancer binding protein (TonEBP), plays a central ...
