Those are all organs that are directly exposed to outside materials.

For the more internal organs, bacteria would have to travel across a skin of digestive tract barrier.

Unless they're present in the womb as the fetus starts growing, I guess.

Indeed, those organs expose to the outside world have reason to cultivate friendly bacteria for no other reason than to take up space, to stop hostile bacteria having a place to take hold.
