  • The exocrine pancreas consists of tubuloacinar glands.
  • A single layer of pyramidal shaped cells forms the secretory acini.
  • The apical cytoplasm (towards the lumen of the acini) is filled with secretory vesicles containing the precursors of digestive enzymes.
  • The first portion of the duct system extends into the centre of the acini, which is lined by small centroacinar cells.
  • These cells form the first part of intercalated ducts.
  • Intercalated ducts are lined by low columnar or cuboidal epithelium.
  • They empty into interlobular ducts, which are lined by a columnar epithelium.
  • Interlobular ducts in turn empty into the main pancreatic duct (of Wirsung), which is lined by a tall columnar epithelium.
