Modeling Transport and Flow Regulatory Mechanisms of the Kidney

Figure 1

Plasma solute concentration, relative to its afferent values (𝐶_𝑖𝐴), along a glomerular capillary at 2 values of plasma flow rates. The “exact” curves were obtained by solving the mass balance and flux equations of an isoporous model; the “approximate” curves were obtained after applying some simplifying assumptions, so that an analytic solution can be obtained for the solute concentration ratio.
