Why do we fart?

1.	Why do we fart?
Answer» A scientific name for a fart is flatus or flatulence. A flatus or fart is a combination of gases (nitrogen, carbon dioxide, oxygen, methane, and hydrogen sulfide) that travels from a person\'s stomach to their **. When a person swallows too much air or eats foods that the human digestive system cannot digest easily, gas becomes trapped in his/her stomach. The bacteria living in our guts also adds to the gas. The only way for this excess gas to exit the body is through the **. The gas that makes flatus or fart stink is the hydrogen sulfide gas.
