WebAn osmotic gradient along the pyramids was evident in control kidneys and disappeared upon establishment of osmotic diuresis. These data suggest that high rates of urine flow through the loop of Henle may wash out the pre-existing countercurrent gradient. This accounts for the inability of the kidneys to concentrate stop flow urine. red patent leather dr martensWebHypoosmotic Renal Medulla High concentrations of sodium and urea in the renal medullary interstitiumare essential for the production of concentrated urine.
