Digestive System - Coggle Diagram

- - - - An enzyme that breaks starch into maltose
  - - - Contraction of the muscles next to the esophagus when food is swallowed
  - - - Folds inside the stomach that helps it contraction and expand
    - - Use to breaks down food fruther
      - Made of:
        
        Hydrochloric acid
        
        Breaks down food
        
        Kills bacteria
        
        Could causes chemical burn if on skin
        
        Pepsin (an enzyme)
        
        Breaks protein into amino acids
        
        Mucus & water
        
        Protects stomach from digests itself
        
        Not enough mucus would results in peptic ulcers (which is when your stomach meets your gastric acid)
  - - - Bile
        
        Produces by liver
        
        Stored by gallbladder
        
        Released into the small intestine by a small pipe at its top
        
        Breaks hydrophobic fat molecules into
        
        Fatty acids
        
        Monoglycerides
        
        Both could be absorb by epithelial tissues on the small intestine's wall
        
        Is an emulsifier
      - Nutrients is absorb through the wall into the circulatory system
  - - - Opening of large intestine
      - Appendix
        
        Good bacteria safehouse
        
        At the end of the cecum
- - - - Valves that stops partially-digested food (chyme) from getting into the small intestine
- - - - The small intestine have 250 square meters of surface area
      - Villi which are small fibers on the folds
        
        Microvilli which covers villi
- - - - Make saliva
    - - Makes bile
    - - Stores bile
    - - Makes pancreatic juice
        
        Helps digest proteins & carbohydrates
