Your stomach contains strong acid that helps break down the food you eat. So you might wonder: if the acid can break down food, why doesn’t it break down the stomach too?

The answer is that your stomach has its own protection system.

The lining of your stomach produces mucus that forms a protective barrier. It also produces substances that help keep the acid from damaging the stomach lining.

And here’s the interesting part: your stomach lining is constantly being replaced because those cells don't last forever.

Basically, your stomach is carrying around acid strong enough to help digest your food while also having to protect itself from that same acid. 😂

The human body really has some impressive ways of keeping things under control.

Medical fact: Your stomach protects itself from its digestive acid using a mucus barrier and other protective mechanisms.
