1. Fold your papers like your teacher shows you. USE 2 STAPLES ONLY!!!

2.  Ingest & chew food  Mechanical Digestion- chewing  Chemical Digestion- amylase- a special chemical called an enzyme that breaks starches into sugars

3.  Transports food from mouth to stomach by way of peristalsis.

4.  Breaks down food and soaks it in acid (gastric juice) to begin digestion of Proteins.  Coated in a thick mucus to protect itself from its own acids.  When there is a hole in this mucus, the acid burns a hole in the stomach called an ulcer.

5.  *Accessory Organ-food does not travel here, but it participates from the side lines.  Digests nutrients  Sends chemicals to appropriate places in the body  Filters waste out of the blood!  Stores vitamins and minerals

6.  *Accessory Organ  Collects waste from the liver  Makes bile – which helps digest fats!

7.  *Accessory organ  Produces juices that aid in digestion  Delivers these juices to the small intestine

8.  Received food from the stomach  Extracts chemicals and nutrients through blood vessels in the villi (finger-shaped structures attached to the intestine wall)

9.  Soaks up water and solidifies waste (makes poop)  Removes waste from the body  Cleans intestine by moving indigestible food (fiber) through them to remove waste.  If too much water taken out = constipation  If too LITTLE water taken out = diarrhea

10.  Removes solid waste from body.
