- - - - Salivary Glands
        -Parotid
        -Submandibular
        -Sublingual
        Secrete salivary amylase which breaks down starch; mucin for lubrication;
        Defensins for bacteria
      - Teeth used for mechanical break down
      - Tongue used for mechanical digestion
      - Pharynx
        
        Serves as a passageway from mouth to esophagus and Prevents food from entering respiratory tract
        
        Esophagus
        
        Passageway from pharynx to stomach closed off by 2 sphincters: grastroesophageal
        and
        Cardiac
        
        Stomach
        where the major breakdown of food occurs divided into 4 parts and have a variety of secretary cells
        
        Cardia receives food from esophagus
        
        Fundus dome shaped part
        
        Body where the bolus is converted into chyme
        
        Antrum last portion of stomach connects to duodenum
        
        Cells
        
        Parietal Cells
        Secrete HCl and intrinsic factor (Necessary for V B12 absorption
        
        Chief Cells
        produce pepsinogen and lipases
        
        Small Intestine
        where majority absorption of nutrients occurs; divided into 3 segments
        
        Duodenum
        uses Enzymes produced in the Pancreas and bile from liver to breakdown nutrients
        
        Connects with Bile Duct from liver and Main pacreatic duct
        
        Jejunum absorption of carbs and proteins occur here
        
        Peyer's Patches and MALT
        
        Ileum lowest part where further absorption occurs
        
        Large intestine
        Majority absorption of water occurs; divided into 3 parts
        
        Cecum found distally to ascending colon and attaches to appendix

        Colon Ascending, Transverse and Descending
        
        Rectum serves as exit for undigested stuffs
  - - - Liver processes nutrient rich blood produce and secretes bile salts which aid in breaking down nutrients
        
        Pancreas
        Produces enzymes for all macro nutrients
        
        Proteases
        
        Amylase
        
        Lipase
        
        Nuclease
  - - - Carbohydrates
        
        Lipids
        
        Nucleic acids
- - - - Duodenum where pancreatic enzymes and bile from the liver are used to chemically breakdown nutrients
        
        Enzymes missing for digestion:
        Salivary Amylase
        Pancreatic amylase
        Lingual, gastric and pancreatic lipase,
        Pepsin
        Pancreatic deoxyribonuclease
