Accessory Glands

  1. Pancreas (amoutn)
    • 1.      Fish have two
    • a.       Dorsal and ventral
    • 2.      All other vertebrates have one
    • a.       Fusion of dorsal and ventral together
  2. Pancreas: part of what system.
    • 1.      Part of endocrine system
    • a.       Difference of exocrine
    •                                                                                                                                       i.      Secrete through ducts to get where they have to go
    • b.      Endocrine
    •                                                                                                                                       i.      Ductless; usually uses circulatory system and the system carries it to its target
  3. Function of pancreas
    • a.      Pancreas releases digestive juices [enzymes] and sodium bicarbonate salts into the duodenum via the main pancreatic duct
    •                                                                                                                                       i.      Sodium bicarbonate salts play a role in reducing the acidity of the chyme that enters the small intestine
  4. Liver Size
    • 1.      Largest gland in body
    • In fish, it’s HUGEEE
  5. Liver digestive functions
    • a.      Liver produces bile
    •                                                                                                                                       i.      Bile is not an enzyme
    • 1.      It is an emulsifier of fat
    • a.      Takes fat and breaks it into small fat molecules 
  6. Bile contains and storage
    • 1.      Bile also has cholesterol, salts, pigments of red cell breakdown (biliruben)
    • 2.      Although made in the liver, its stored in the gallbladder
  7. True or False:
    Gallbladder is another accessory gland.
  8. Function of gallbladder
    • a.      Most vertebrates have a gallbladder (not an accessory gland)
    •                                                                                                                                                                                                               i.      Some birds don’t
    • b.      Function: concentrates the bile and stores the bile
    •                                                                                                                                                                                                               i.      Bile enters the duodenum through the common bile duct
