| Saliva | has enzyme that begins chemical digestion of carbohydrates and turns complex carbs into simple carbs. |
| Esophagus | tube that transports food from mouth to the stomach |
| Stomach | squeezes its contents with muscular contractions to physically and mechanically digest food (stomach acid) produces chyme |
| Pancreas | produces pancreatic juice that nuetralizes acid in chyme producing bile |
| Liver | Produces and secretes bile |
| Gall | stores bile and then squeezes it into the small intestine |

| Large Intestine | stores, compacts, and then eliminates indigestible material from the body |

| Mineral | a nutrient that is nonorganic and is essential to function of the body |
| Chyme | the after product of food after chemicl and physicl digestion in the stomach |
| Mastication | chewing |
| Chemical Digestion | The breaking down of chemicals into smaller chemicals |
| Mechanical Digestion | The physical breaking down of an object |
