WebWhile passing through renal tubules, water and a lot of other substances are reabsorbed making filtrate concentrated. This also gradually results in an increase in the concentration of urea as it is not reabsorbed like water or glucose. Some substances like K+, H+ are also secreted (not urine). WebSo, the glomerular filtrate concentrates as it moves down through the descending limb. Reabsorption is minimum in the ascending limb. This limb is impermeable to water but electrolytes can be transported actively or passively. So, as the concentrated filtrate moves upward it gets diluted due to the passage of electrolytes to the medullary fluid.
