Four Functions Of Digestive System
- 1.ingestion-the intake of nutrients
- 2.digestion-the breakdown of nutrients
- 3.absorption-the assimilation of nutrients
- 4.egestion-theelimination of wastes

Stomach Not Digesting itself?
Epithelial Muscosa
-
Liver!!!
- Manufactures
- Stores
- Detoxifies
-
Foods into Three Groups
- Starch-Amylase:sugars
- Fat-Lipase:fatty acids & glycerol
- Proteins-Pepsin,Trypsin,Chymotrypsin,Peptidase:amino acids
