obviously you're going into less and less oxygen as you go down so presumably you don't have pure Anor robes in the mouth but I I know from the little bit I remember about working in an ER whenever somebody received a bite you know you would think ah how bad can a bite be we we were really conditioned to remember that those are some of the dirtiest wounds a human can have and no less dirty than a feces soiled wound so even at the proximate end of that U of that bacterial lining it's these are really frightening bacteria um but but can you tell me anything about how the bacteria change as you progress along that the length of that which is by the way that's a very long tube so it's not just measuring here to here like you have to understand the Tor you know the listener would have to understand how tortuous the small intestine and the colon can be yeah I mean the the primary thing that changes is this Anor robic part so obviously your mouth there's lot of oxygen exposure and then as we said when you get to the distal colon there's no Oxygen there
