Thanks, Trinoc. I didn't make my message very clear. "Inhaling and exhaling" is not the same as cellular respiration, that is clear. Physiological respiration (according to your link) is a 3-step process, one of which involves inhaling and exhaling. Either way, inhaling and exhaling is not the same thing as physiological respiration either.
Thank you for helping to make my podcast episode on this topic more clear. I went back and edited that episode as a result. This part of the podcast was a very small part of the whole, so it was easy to edit.
