On the other hand, it is evident that GFR is conditioned also by perfusion, though in a manner which is not exactly describable so far
A linear relationship between GFR and RBF could be presupposed only under physiological conditions (the point of equilibrium is attained within the capillary)
If the hydraulic conductivity declines in relation to the plasma flow velocity under pathological conditions, the point of equilibrium “escapes beyond the horizon” and GFR does not parallel the RPF. In a limit case, GFR ceases to be dependent on RPF at all (Fig.25)
