Morphological features along vascular pathways.
(A) Example of the arterial pathway from a single root with a diameter-defined Strahler order, where the color denotes the order number. (B, C) Morphological features of the diameter, length, and number of elements with respect to the element order for arteries (B) and veins (C). The symbols denote the evaluated values and the solids denote regression lines of the form log10 q = a + bn, where two regression lines are fitted for the data from n ∈ [1, 5] and n ≥ 6 excepting the last order number. The values of the intercept a, slope b, and determination coefficient R2 are shown in the graphs. In (B), the fitting curve given by the measurement of rat vessels [33] is also plotted by ∝nb.
