Pancreas

• 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 (zymogen granules) 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 clear 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.
