Notes: Intro to Digestive System

4. (1) Main Digestive Organs
Oral Cavity = Lips, Teeth, Tongue
Esophagus
Stomach
Small Intestine (Duodenum, Jejunum, Ileum)
Large Intestine (Colon)
Rectum & Anus

5. (2) Assistant Digestive Organs
Liver
Pancreas
Gallbladder
Appendix

6. (3) Function Break down food stuff
Metabolize biomolecules (carbohydrates, lipids, protein)
Absorb useful inorganic and organic nutrients
Expel non-useful compounds as waste

9. (4) Digestion in the Oral Cavity
Overall: Break food into smaller chunks & Moisten.
Biomolecule Metabolism: Carbs Only.
Tongue = Manipulation, Tasting
Teeth = Grinding & Break Down
Saliva = Moisten & Metabolize Carbs

12. (5) Saliva Released Parasympathetically upon the sight/smell of food.
Moisture  Needed for Esophageal Travels
Contains:
Amylase = Enzyme  Digests Carbohydrates
Lysozyme = Enzyme  Digests Bacterial Cells

14. (6) In The Esophagus Approximately 10inches long
Between Oral Cavity & Stomach
Composed of Smooth Muscle No Food Digestion Here 
Muscle Contractions:
Peristalsis  Wave Like Contractions
Moves food through like tube of toothpaste
