Digestion System - Coggle Diagram

- - - - mouth
      - parnyx
      - esophagus
      - stomach
      - small intestine
      - large intestine
    - - submuosa
        
        elastic fibers to maintain shape
      - MUSCULARIS LAYER:
        
        layers of smooth muscle
      - Mucosa
        
        Epithelium
        
        simple colomnar for absorption
        
        Lamina propria
        
        contains blood and lymphatic vessels and lymph node for nourischment and immunity
        
        Mucous membrane
        
        produces mucus for reduction of friction and protection
      - SEROSA
        
        outer coverings of the tract and produces seroud fluids for lubrication
  - - - secretes pancreatic juice made by pancreatoc acinar into duodenum
    - - functions
        
        protein metabolism
        
        deaminates amino acids, forms area synthesizes pasma protiens, converts certain amino acids into other amino acids
        
        storage
        
        stores glycogen, iron, and vitamin A, D, and B
        
        lipid metabolism
        
        oxidezes, fatty acids, synthesizes lip-protiens, phospholipids and cholesterol, converts excess portions of carbohydrate molecules into fats
        
        blood filtering
        
        removes damaged red blood cells and foriegn substances by phangcytesosis
        
        carbohydrate metabolism
        
        polymerizes glucose breaks down glycogen to clucose, converts momcarbohydrates to glucose
        
        detoxification
        
        removes toxins from blood
        
        secretion
        
        produces and secretion bile
    - - mixing and holding chaber
      - forms chyme from food
      - 3 parts:
        
        Pylerus (pyleric)
        
        lower narrow section
        
        body
        
        central main part
        
        cardia and the fundus
        
        enlarges opening next to esophagus (upper section): temporary storage
    - - stores excess bile for liver
      - stores to realease into small intestine
      - under surface of liver
    - - digestion b bacteria
      - absorption of water ane salt
      - form store and eliminate feces
    - - functions
        
        chemical digestion
        
        intestinal glands secrete intestinal juices
        
        absorption
        
        water and nutrientsare absorbed
        
        mechanical digestion
        
        segmentation and peristalisis
      - 3 sections
        
        Jejunum
        
        borbtion and in circular fold increases surfsace area
        
        Ilium
        
        absorbs vitamins and bile salts
        
        Duodenum
        
        chemical digestionn
        
        pancreas>apancreatic juice
        
        ;iver>bile>fats
- - - - produced by brush- border cells furthe breakdown further breakdown protiens and carbs into thier monmers
    - - reduce peptides to amino acids
    - - reduces sucrose (cane sugar) to glucose and fructose
    - - reduces lactose to glucose and galacose
    - - reduce maltose 9malt sugar) to glucose
    - - reduces fats into fatty acids and glycerol
    - - breaks down peptide bond in protien (secreted by chief cells
    - - secretes by parietal cells and helps intesitine absorb vatamin B12
    - - produces mucus that protects the stomach lining
    - - (secreted by parietal cells) kills bacteria and denatures/ digests proteins
  - - - small interstine
    - - pancreas
    - - small intestine
    - - stomach
      - small intestine
