Medullary hypertonicity

WebRenal medulla, hypertonicity Concentration of urine is made possible by generation of osmotic gradients in the renal medulla.This involves a counter-current process which pumps ions without water from the loops of Henle into the medullary interstitial fluid.When the filtrate passes down the collecting ducts lying parallel to the loops of Henle, water passes … WebThis low flow represents a compromise between the need to deliver nutrients to the medulla and the need to avoid washout of medullary hypertonicity. Second, and far more significant, the kidney uses a hairpin configuration, with the descending and ascending vasa recta both entering and leaving through the same region, thus creating an efficient …
