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.
