Order distribution of the myogenic regulation parameters. For orders 5–7, the values (boldface numbers) were obtained from a fit of Eq. 2 to data on isolated vessels (Liao and Kuo, 1997). For the purpose of interpolating to vessel orders 8 and 9, the active properties for vessels of order 10 were set to zero assuming they show no myogenic response. Data for in-between orders were extrapolated or interpolated from the measured ones.
