What happens to fish bones that we eat--do they get dissolved or pass through?

Pass through or get stuck. Eat some bread after swallowing a fish bone, it will help it through.

Don't try it, because your body doesn't have the power to dissolve it. You can get into real troubles. Think about it before eating fish bones, because they can also get stuck on your throat, and give you a bad moment.

first why do you ask this, second, they pass through
