I might get downvoted for this, but here it goes: Lets say that your life depends on intestinal ventilation, and you've got a steady flow of oxygenated fluids

I might get downvoted for this, but here it goes: Lets say that your life depends on intestinal ventilation, and you've got a steady flow of oxygenated fluids going into the uh... places... and you need to go number 2? Is it a race to see how quick you can "go" before you get hypoxic and die? Does the constant flow of oxygenated material flush out any waste? It's like wondering "how does Cat Dog go #2" I suppose. But... really. How does it?
