Flies and the human body?

Question

there was a fly flying round my room and then it disappeared, can flies life in the human body if somehow it got in?

Answer 1

EWWW that would suck, but flies die after a day. plus if it got into your stomach...the acid would just kill it...ew omg thats so gross. but yeah, dont worry about it.

Answer 2

I don't think fly could survive in a human body, it needs oxygen. If it could enter your body through the hole, than it will die certainly caused of fluid we produce as a barrier.  

Answer 3

There was an old lady who swallowed a fly.

Perhaps she'll die.

She swallowed a spider to catch the fly,

which wriggled and ....

etc.
