  • Exocrine Pancreas
    • Releases salts/enzymes to the duodenum via a duct
      • Because the duodenum enterocytes are so specialized for absorption, they are less effective at secretion and require the aid of pancreatic enzymes to help the digestive enzymes manufactured in the brush border
    • Releases bicarbonate
      • Neutralizes low-pH gastric acid entering the duodenum 
    • Releases amylase
      • Breaks down polysaccharides (starches) and glycogen
    • Releases lipase
      • Breaks down triglycerides
      • Chemically digests emulsified lipids
    • Releases trypsinogen and chymotrypsinogen
      • Breaks down proteins
