1. The Accessory organs: Pancreas and liver
Pages

2. General Idea: Organs that add digestive enzymes
Empty at the Duodenum
Hepatopancreatic ampulla
Series of ducts
Pancreas  digestive enzymes via pancreatic duct
Liver  Bile via the hepatic & common bile duct
Gall Bladder  Concentrated Bile via the cystic & common bile duct

4. The Pancreas General Characteristics Pancreatic Juice
Both Endocrine & Digestive Gland
Acinar Cells – digestive function
Produce pancreatic juice
Pancreatic duct  hepatopancreatic ampulla  duodenum
Pancreatic Juice
Pancreatic amylase  Carbohydrates
Pancreatic lipase  fats
Trypsin, Chymotrypsin, Carboxypeptidase  Proteins

5. Nucleases – nucleotides
Bicarbonate ions – buffer to neutralize acidic chyme
Regulation
Parasympathetic impulses
Secretin (hormone)
Cholecystokinin (hormone)

7. Liver General Characteristics Many Different Functions BIG!
Right Side of Abdominal Cavity
Reddish Brown  Ferritin (Iron)
Hepatic Lobules
Hepatic Sinusoids, Hepatic Portal Vein
Kupfer Cells
Many Different Functions
Metabolic
Storage
Destroy/remove damaged RBC’s
Detoxification
Blood Resevoir

9. Liver and Gall Bladder Only Digestive Function: Produce Bile
Emulsification of Fats – smaller droplets
Water, Bile Salts*, Bile Pigments (bilirubin & biliverdin), cholesterol, electrolytes
Hepatic Lobules  Bile Canaliculi  Common Hepatic Duct  Common Bile Duct  Hepatopancreatic Ampulla  Duodenum
Better Absorption of fatty acids, cholesterol & Vitamins
Gall Bladder: Store and concentrate the bile
Cystic Duct  Common Bile Duct  Hepatopancreatic Ampulla  Duodenum
Stimulated by Cholecystokinin
Gall Stones, Cholecystectomy
