Maybe the same channel? It did appear to be an enema of some sort, so the evacuation route might be the same. Farting contests might be about to get really intense.
The butt being able to absorb the oxygen doesn’t really also mean that there’s a mechanism for the butt to expel the carbon dioxide though. We do that through our lungs by exhaling and we clearly don’t expel enough carbon dioxide through non-exhaling methods to keep up with the amount we need to exhale.
That does raise a good point. I don’t know human biology well enough to give an educated answer though. If oxygen can be absorbed rectally via this fluid, perhaps the fluid can exchange CO2 the same way though? Or maybe via a different fluid? Bit rough on the ass but any port in a storm I suppose.

The co2 is farded out
