ALIMENTARY SYSTEM
AVIAN DIGESTIVE TRACT



Structure

  • 2 lobes
  • Dark brown coloured (except just after hatching where it is yellow)
  • Right lobe larger than left lobe
  • Ventral and caudal to the heart (as there is no diaphragm)
  • Thin capsule
  • Indistinct lobation
  • 2 bile ducts enter the distal duodenum, one from each lobe of the liver
  • The duct from the right lobe is connected to the gallbladder
  • Hepatic lobules indistinct (except near hilus) due to a lack of perilobular connective tissue
  • Avian bile aids the emulsification of fats and contains amylase and lipase
