									GallBladder
      • Stores Bile
      • Releases Bile into the
        Cystic Duct which
        joins with the
        common Bile Duct
        and empties into the
        duodenum
Gallstones
     • Cholesterol
       percipitates and forms
       crystals
     • Very painful and
       blocks bile secretion
       into the cystic duct
Small Intestines
           • Receives chyme
             from Stomach
             and secretions
             from pancreas
             and liver
           • Chemically and
             Mechanically
             breaks down
             chyme
           • Absorbs nutrients
• Duodenum – receives
                          Parts of SI
  bile from liver and
  gallbladder and
  pancreatic secretions
• Jejunum – Primary
  area of Absorption
• Ileum – contain an
  abundance of lymph
  nodes
             Other Structures
• Mesentery – connects SI
  to post. Abdominal wall
  and supports blood
  vessels, nerves and
  lymph vessels
• Greater and Lesser
  Omentum – Apron-like
  structure that protects
  extends from stomach
  and covers the SI. The
  “policeman” of the
  Abdomin
Mesentery
                  SI Structure
• Intestinal Villi – tiny
  projections that
  protrude into the
  lumen of the
  alimentary canal
• Lacteal – Lymphatic
  capillary
• Intestinal Glands –
  secrete mucous
               Secretions
• Goblet Cells – secrete mucous
• Peptidases – break down peptide bonds
  into AA
• Sucrase, Maltase, and Lactase – splits
  disaccharides into simple sugars
• Intestinal Lipase – splits fats into fatty
  acids and glycerol
                         Absorption
•   Fatty Acids enter Epithelial Cells
•   FA are then used to synthesize Fats within the ER.
•   Fat is then clustered and coated in PRO, called chylomicrons
•   Chylomicrons are then enter lacteal and make way to blood
