One example is vomiting. Vomiting is expelling food from your stomach. Even though this is disgusting, this has happened to everyone.

Another example is heart burn. Heart burn is stomach acid that enters your esophagus. What lots of people hate the most,is getting heart burn

My final example  is Nausea. Nausea is an ill feeling in your stomach. Lots of people get nausea and nobody really likes it.

Even though it is the digestive system,there are some consequences to pay.
