2. Pancreas

3. Pancreas Anatomy Accessory digestive organ
Enzymes for chemical digestion in the small intestine
Hormones for carbohydrate metabolism
Anatomy
12.5 cm x 2.5 cm
Connected by 2 ducts to duodenum
Head, body and tail
delicate, fragile organ
difficult to repair after injury
difficult to diagnose and treat pancreatic diseases

4. Pancreas Histology - clusters of glandular epithelial cells
1% are endocrine cells in pancreatic islets (islets of Langerhans)
glucagon (alpha cells)
insulin (beta cells)
somatostatin, pancreatic polypeptide (delta cells)
99% are exocrine acinar cells
secrete pancreatic juice

5. Pancreas Acinar cells secrete pancreatic juice into 2 larger ducts
Larger - pancreatic duct
joins common bile duct from liver, gallbladder
enter duodenum at hepatopancreatic ampulla with common duct
Smaller accessory duct empties into small intestine upstream
