- - - - Functions:
        Dissolving food for Taste and Digestion
        Mucos: Mostions food, lubricates oral surfaces
        CI- Ions activate the Amalyse
      - Saliva contains salivary amylase, which is important when it comes to breaking down Carbohydrates (like starches)
      - Produced by the Salivary Glands. There are three pairs.
        Composition of Saliva differ per each pair.
        
        Partoid Glands: Watery Saliva, Amalyse
        
        Sub-mandibular Glands: Thicker Mucose, Amalyse
        
        Sublingual Glands: Mostly Muscos, little Amalyse
- - - - The Fundus: Top portion of the stomach. Where the stomach meets the esophagus
      - The Body: Middle portion of the stomach
      - The Antrum of the stomach: Bottom portion of the stomach, where the stomach connects/meets the duodenum
    - - Goblet cells produce alkaline mucus
      - Mucus surface layers trap a bicarbonate fluid beneath it
      - Gastric Pits
        
        Mucus Neck Cells: Secrete mucus
        
        Parietal Cells: Secrete HCL and intrinsic factor
        
        Chief Cells: Produce pepsinogen and is activated by HCL in the stomach
      - Rugae: Folds of the mucosa
