rat inside stomach

I have seen in CSI episode "Lab rats" a rat bursting out of human carcass stomach...
So I was curious, is there any chance, whatsoever,that rat would get inside of human body digestive system...
and if possible, could you link me to books and articles about a particular case, if there is any of course.
Thx in advance

yes, It is possible for a rat to be found inside the corpse of a human or any other animal for that matter. But it's not likely that the rat entered the corpse's stomach by crawling into its mouth, down its throat, through the intestine and then finally, coming to rest inside the stomach. If one is inside the body the( stomach area,) the rat most likely gnawed a whole directly from the outside into the corpse's stomach and then entered he stomach from the whole it made. The rat wouldn‘t “burst“ out of the corpse but simply exit through the whole it made earlier.

There have been cases of rats being found in the mouths of dead people though. I’m sorry I don’ have any links to give.
