The Digestive System

It helps us move our muscles.

It breaks down food for energy, absorbs nutrients, and removes waste.

It helps us breathe.

It controls our heartbeat.

Mechanical digestion breaks food into smaller pieces using physical force, while chemical digestion uses special juices and enzymes to break food into nutrients.

Mechanical digestion uses enzymes to break down food, while chemical digestion uses teeth and muscles.

Mechanical digestion happens only in the stomach, while chemical digestion happens only in the mouth.

Mechanical digestion absorbs nutrients, while chemical digestion forms solid waste.
