Why does a person vomit if he/she sees a gory scene? What kind of defence mechanism is the body puttin up?

Thanks to everyone, you have been very helpful!
Fight or flight reflex. It can make your body have very specialized reactions to situations that ultimately boil down to self preservation.
It’s because of adrenaline. When we see a gory body, our mind thinks “danger” and adrenaline is made to “prepare” the body for danger. One of the things adrenaline does is suppress appetite and digestion. Depending on how much you’ve eaten, how shocked you are, and probably other things, getting scared can basically make you throw up.
When you see a gory scene, it provokes a fight of flight response in some people from deep down in our lizard brain from back in the caveman days. One outcome of fight or flight is to puke because our body is ejecting whatever we recently ate in order to be able to escape without it weighing us down or making us more slow than we want to be.
Curious to see the answer to this as well; my immediate thought is that it’s the body getting rid of unnecessary immediate energy drains (ie: digest food or run like hell, not both) but that’s probably the kind of answer that shows up in Reddit Fails Or The Day.
(Typo left in intentionally because it fits the theme)
Vomiting is your body ejecting something it perceived as harmful.
So if you ate poisonous berries, you would puke them out before they cause more harm.
If somebody in your tribe (think cavemen times) puked, you probably ate the same food and the sooner you can get it out of your body, the better.
It’s the same for yawning.
When someone in your tribe yawns and goes to sleep, you should do the same.
