What happens when we throw up? Physically what makes the stuff come out from our stomach?
In: Biology
There’s a few different muscles involved that do things that cause your body to prepare to vomiting, such as closing off the glottis (where your vocal cords are), opening up the esophageal sphincter and esophagus, then your abdominals contract to squeeze the stomach really hard. At this point, the only place for its contents to go is up and out of the esophagus.
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.
So how does only food come out and not all the acid?
