Why do we burp and fart?

We burp and fart because air gets in. It comes out of our mouths or bottoms. Burps can be loud. Farts can smell funny.

We burp and fart because extra air gets inside us. Some air goes down when we eat, drink, or talk. A burp is air coming back up. A fart is gas made when food is being changed in our belly, then it comes out the other end. It is like letting air out of a balloon so it does not feel too full.

Burps and farts happen when gas is inside your body. A burp is mostly swallowed air that comes back up from your stomach. A fart is gas that travels through your intestines, the long tubes that handle food after your stomach. Tiny living helpers there make some gas while breaking down food. Fun fact: beans can make more farts because those helpers love parts of beans that your body cannot break down alone.
