Fig. 3

Rendering of the human kidney vascular network, with vessels coloured according to A Strahler order and B topological generation. Ci Plot showing the number of vessels per truncated Strahler order, with fit for the log plot to calculate branching ratio. Cii Truncated Strahler order against cumulative vascular volume fraction. D One of the VOIs with all glomeruli segmented. E A region within the VOI in (D) segmented at 2.6 µm per voxel, showing connection down to afferent glomeruli. Inset shows the six glomeruli that were connected back to the whole network. The five red arrows indicate glomeruli arising from non-terminal arteries, while the black arrowhead indicates a glomerulus arising from a terminal artery.
