Learning Objective
I can describe how my digestive system breaks down food into nutrients my body can use.
- 1
The four main jobs of your digestive system are ingestion, digestion, absorption, and elimination.
- 2
Digestion starts in your mouth, where your teeth break down food and saliva starts to break down some biomolecules.
- 3
The small intestine is where most of the nutrients from your food are absorbed into your body, and the large intestine reabsorbs water.
