Categorization of systemic arteries by radius exponent in the two canine data sets in literature.

Locality	References	x s	Range of radius (mm)	Expected wall property	Expected range of Reynolds number
Proximal		xs ~ 2.3		Elastic	400–11001
Dog	Milnor (1982)	2.32 ± 0.06	0.65–9.5
Dog SMA	Sherman (1981)	2.30 ± 0.16	0.5–1.5
Intermediate		xs ~ 2.7		Elastic‐muscular	42–400
Dog	Milnor (1982)	2.65	0.225
Dog SMA	Sherman (1981)
Peripheral		xs ~ 3.0		Muscular (rigid)	0.13–4
Dog	Milnor (1982)	2.95	0.075
Dog SMA	Sherman (1981)	3.10 ± 0.244	0.011–0.096

x, radius exponent, defined by equation (1 or 3; s, systemic; SMA, superior mesenteric artery. Sources of data sets were table 2.3 (Milnor 1982) and table III (Sherman 1981).

¹Nichols et al. (2011); ²estimated from equation 35 and Mayrovitz and Roy (1983); ³from Kizilova (2006); ⁴does not include the rank 4 arterial data (Sherman 1981) as an outlier.
