Mechanical vs. Chemical Digestion Mechanical digestion is a physical

process. The food is getting broken into smaller pieces. Can you think of a place where this

happens? Chemical digestion is a process where

the food is chemically broken into its most basic parts. Where do you think that this might happen?

Mechanical Digestion

Mechanical digestion = physically breaking apart the food.

Chemical Digestion

Chemical Digestion = enzymes (chemicals) break down the food into its parts.

Let’s begin. You may now eat your candy and start on the amazing digestive journey!

The Mouth

The teeth mechanically digest the food by breaking it up into small pieces.

Your saliva (spit) has enzymes that begin to chemically digest the food while in your mouth.

The Esophagus

The esophagus is the tube that goes from your mouth to your stomach.

Food moves when the muscles of the esophagus contract causing the food to be moved down. This is called peristalsis.

The Stomach The stomach is where food goes after you

swallow it. Both mechanical and chemical digestion

occur in the stomach. The stomach churns to mix the food with the

acid. This is mechanical digestion. The stomach then chemically digests the food

with a couple of chemicals. ○ Pepsin breaks down protein.○ Hydrochloric Acid kills all bacteria and allows for

the food pepsin to work well.
