Question

What happens when we throw up? Physically what makes the stuff come out from our stomach?

In: Biology

Answer 1

Your brain finds out something is bad in your stomach and then your brain tells your diaphragm ~ the muscle that makes you breathe ~ to move down so that your muscles in your mid section can squeeze your stomach reeeeally hard to push the bad stuff out of your mouth. Like squeezing a toothpaste tube.
