Why does the sight of blood etc make people feel sick, seeing it not suffering an injury?

Interested to know what causes that reaction. Not the person suffering the injury but people who see it. Doesn’t affect all people and you can get desensitised but what is it about the sight of inside stuff that makes you feel sick?

idl why that phobia is caused. I have it. but it only triggers me when there is a pool of blood. a little is fine. Might have stemed from anything. accidents i saw on road, my injuries, who knows. but I just know that i couldnt go on to become a doctor like i dreamt of when i was a child. so i m still soul searching for the perfect fit career despite already working
