Figure 4.
Longitudinal tissue Po2 profiles with and without axial diffusion (μLD = 0.35, vRBC = 1.0 mm/s). Top: cortex geometry with Po2 at 15 μm from the capillary endothelium. Bottom: glomerulus geometry with Po2 at 10 μm from the capillary endothelium. Solid line: numerical model with axial diffusion. Dashed line: analytical fit to the simulation with axial diffusion. Dash-dotted line: numerical results without axial diffusion. Dotted lines: analytical fit to the simulation without axial diffusion. The analytical fits use the IVR coefficients defined in the text.
