Categorization of mammalian arteries by locality in terms of radius, arterial wall property, and consequently radius exponent.

The range of the radius presented in each classification of systemic and pulmonary arteries comes from Struijker‐Boudier's (2009) figure 1 and Suwa and Takahashi's (1971) table 1(a), respectively. r stands for radius; x, radius exponent defined by equation (1 or 3. Suffixes p and s indicate pulmonary and systemic, respectively. Although the lower limit of the vessel radius is common to that of capillaries, our arterial model does not conceptually include the capillary vessel.

^1,2indicate vessel types to which we applied our elastic and rigid arterial models, respectively. Data of x came from table 1 (Dawson et al. 1999), table 4 (Horsfield and Woldenberg 1989), figure 2D (House and Lipowsky 1987), P. 15 (Kassab and Fung 1995), table 1.3 (LaBarbera 1995), table 1 (Mayrovitz and Roy 1983), P. 36 (Nakamura et al. 2011), P. 443 (Sherman 1981), tables 4 and 5 (Singhal et al. 1973), and table 3 (Suwa and Takahashi 1971).
