| A | B |
|---|
| Liver (make enzymes? touches food? Chemical made here? Nutrient acted on?) | No, no, bile, fats |
| Pancreas ((make enzymes? touches food? Chemical made here? Nutrient acted on?) | Yes, no, pancreatic juices/everything |
| Gallbladder ((make enzymes? touches food? Chemical made here? Nutrient acted on?) | No, No, none (stores bile), none |
| Mouth (make enzymes? touches food? Chemical made here? Nutrient acted on?) | No, yes, none, physical change on most foods -chemical change on carbs |
| Salivary Gland (make enzymes? touches food? Chemical made here? Nutrient acted on?) | Yes, no, saliva and salivary amalase/carbs |
| Esophagus (make enzymes? touches food? Chemical made here? Nutrient acted on?) | No, yes, none, none |
| Stomach (make enzymes? touches food? Chemical made here? Nutrient acted on?) | Yes/yes/pepsin, & hydrochloric acid/carbs, fats & protiens |
| Large intestine (make enzymes? touches food? Chemical made here? Nutrient acted on?) | No/yes/none/everything |
| Small Intestine (make enzymes? touches food? Chemical made here? Nutrient acted on?) | No/yes/none.everything |
| Teeth and Tongue | cause physical change in food |
| Esophagus | pushes food from mouth to stomach |
| Small intestine | most digestion occurs here (absorption of nutrients) |
| Liver | largest organ |
| Large intestine | absorbss H2O, vitamins and minerals into the body |
| Appendix | has no funcion |
| Stomach | produces enzymes that digest protien, has hydrochloric aid that helps break food into more pieces |
| Pancreas | makes enzymes that digest carbs, fats and protiens |
| Roughage | cleans your system (fruits and vegetables) |
| Digestion system of an Ameba and Paramecium | food vacuole form around food particle, digestive enzymes secreted and digestion products absorbed through the membrane between vacuole and cytoplasm. Intracellular digestion!! |
| Digestion system of a Hydra | food ingested through mouth, specialized cells in inner layer of body wall recieve partly digested food substances and complete digestion in cell vacuoles. Enzymes secreted into cells and gastrovascular activity is both Intra and Extra cellular digestion!! |
| Digestion system of an Earthworm | Enters mouth passes digestive tract in one direction. Digestion is extra cellular!! w/ intestinal absorption of digestion products. |
