a
The airflow splits are calculated as the percent of the total mass flux entering each compartment across each cross-sectional or z slice shown in Figure 1. Total airflows that pass through each compartment are thus calculated as a mass balance of airflows that cross each z slice as well as across slices in the x plane bisecting the nasal airways into dorsal and ventral regions.

Note that the sum of the surface areas and volumes for each compartment ignores the nostril, which is included in the totals presented in Table 1.
