Stomach - Peristalsis

In the stomach body where digestion happens, your food is rolled around, squished and smushed.

This is done by something called peristalsis.

The outside parts of your stomach are called the walls, and the walls of your stomach squeeze and push the food around your stomach so that it gets smushed up into smaller pieces.
