Food and drink enter your stomach and dissolve in a strong acid bath, then exits your stomach into your intestines for a good old squeeze over many hours.
When you pee or poo, it doesn’t burn at the exits.
Surely some stomach acid must enter the intestines? Where does the stomach acid go? What happens to it?

Your body (specifically your liver) produces a substance called [bile](https://en.wikipedia.org/wiki/Bile), which is slightly basic. This mixes with the chyme (the stomach acid + food soup coming from your stomach) to both help digestion and to neutralize the acid, so that it doesn’t damage the rest of your body.
