What happens to food after you take a bite

Introduction

Digestion turns food into energy and building materials for your body, starting in the mouth.

Digestion starts in the mouth

Chewing and saliva break food into smaller pieces and begin chemical digestion.

The role of the stomach

Stomach acids and enzymes further break down food into a semi-liquid mixture.

Absorption in the intestines

Nutrients are absorbed in the small intestine through tiny structures called villi.

Waste removal

Unused material moves to the large intestine and is eventually eliminated.

Key takeaway

Digestion is how your body transforms food into fuel for every system.
