These experiments would seem to prove that no special spiracles are used for inhaling and others used for exhaling, but rather that all are alike in this respect, as the abdomen expands air is taken in and as the body contracts the gases are exhaled.

Optimal respirator settings in assisted respiration
Medical & Biological Engineering, 1974An analysis of assisted respiration, based on a linear, first-order lung model, has been performed using rectangular, sine and ramp input pressure waveforms. The results of the analysis have been applied to predict optimal respirator settings. The criterion of a simultaneous minimisation of the average alveolar pressure and ventilatory work per minute ...
