- - - - Produces and secrets 22+ enzymes that enter the duodenum
      - Duct cells produces bicarbonate which is an alkaline substance which helps neutralize acids
- - - - Connected to the small intestine (jejunum to ileum) to the posterior abdominal wall
    - - Connected to the transverse and sigmoid colon to the posterior abdominal wall
    - - Connected to the lesser curvature of the stomach and extends up to the liver
    - - Connected to the greater curvature, drapes over the abdominal organs and comes back up over the transverse colon to the posterior abdominal wall
- - - - Prevents reflux of acid back into the esophagus
    - - Regulates the amount of chyme moving into the small intestine
    - - Gastric folds that increase surface area and storage capacity
  - - - Produce hydrochloric acid and intrinsic factor which is needed to absorb vitamin B12 which is needed to produce erythrocytes
    - - Secrets pepsinogen which when mixed with acid from parietal cells becomes pepsin which is an enzyme that breaks down proteins
- - - - Mouth
        
        Teeth
        
        Toungue
      - Small Intestine
        
        Segmentation
        
        Movement of food forward and backward to mix up contents
        
        Peristalsis
        
        Movement along tract distally
      - Stomach
        
        Muscles of stomach churn food into chyme

  - - - Pancreas
      - Urinary Bladder
      - Duodenam of Small Intestine
      - Ascending Colon
      - Descending Colon
      - Rectum
- - - - Slow down movement of chyme
      - Increase surface area for ample amount of absorption
    - - Secrete Alkaline Mucous
        
        Alkaline neutralizes acids from stomach
        
        Mucous offers protection
    - - Secrete watery intestinal juice to keep contents in liquid state
    - - Collection of lymphatic tissue to fight of foreign cells
    - - Where the Ileum of the small intestine meets with the cecum of the colon
      - Prevents thh movement backward into the small intestine
- - - - Made up of three stripes of longitudinal muscle
      - Function to pull/contract colon into pouches that are called haustra
    - - Sac/pouches of the colon
    - - Fat filled visceral periotinum located on the colon
      - No known function
