It’s often seen in film/books/etc. that when someone receives a chest injury, is smashed against a wall or similar, he coughs up blood or has blood coming out from his mouth. Does this actually happen? Why?
If the lungs get damaged it makes sense that blood gets coughed up, but what about injuries that affect other organs?
In: Biology
They don’t. It’s just a good visual representation for the movies that clearly, easily, and quickly depicts “he’s really hurt”
