Relationship between normalized crown volume (V_c/V_c,max) and normalized number of capillaries (N_c/N_c,max) for the symmetric trees of various species and organs shown in a log-log scatter plot. RCA, right coronary artery; LAD, left anterior descending artery; LCx, left circumflex artery; PA, pulmonary artery; PV, pulmonary vein; SMA, sartorius muscle arteries; MA, mesentery arteries; OV, omentum veins; BCA, bulbular conjunctiva arteries; BCV, bulbular conjunctiva veins; RMA, retractor muscle artery. The scaling exponent (Equation 6) and R² for each species and organs summarized in Table 2 are consistent with 3/2 or 4/3 exponent. The values of exponents, the confidence interval and R² for each species and organs are summarized in Table 2.
