Digestive system - Coggle Diagram

- - - - Chewing breaks up large pieces of food and mixes it with saliva.
      - Carbohydrase in saliva digests some starch into maltose.
    - - Food is moved by peristalsis and some Carbohydrase digests starch as it was swallowed.
    - - Peristalsis churns and mixes food with gastric juice.
      - Acidic gastric juice contains protease which digests proteins into polypeptides.
    - - Bike produced by the liver is released and emulsifies large globules of fat into small droplets.
      - Carbohydrase digests starch into maltose and maltose into glucose.
      - Carbohydrase digests sucrose into glucose and fructose
      - Carbohydrase digests lactose into glucose and galactose
      - Lipase digests lipid into glycerol and fatty acids into a ratio of 1:3
      - Protease will digest proteins into polypeptides
      - Peptides will digest polypeptides into amino acids
  - - - Absorbable substances are absorbed into the bloodstream
      - What can be absorbed
        
        Monosaccharides
        
        Amino acids
        
        Glycerol and fatty acids
        
        Minerals and vitamins
        
        Water
    - - Water is absorbed
      - Faeces are formed
- - - - Chewing
        
        Teeth in mouth bite into food, cutting it into smaller pieces
      - Peristalsis
        
        Stomach churns food and mixes it with digestive juices
        
        Food in oesophagus gets pushed down to the stomach by peristalsis
  - - - Carbohydrates are digested by carbohydrase
      - Proteins are digested by protease
      - Fats are digested by lipase
    - - They are biological catalysts made of protein. They speed up chemical reactions without themselves being chemically changed at the end of the reaction.
      - Specific to the reactants they work on
