    The main duct in the pancreas that transports pancreatic juice to the small intestine.
  • Acini
    Clusters of secretory cells in the pancreas that produce inactive digestive enzymes.
  • Acinar Cells
    Cells within acini that secrete inactive digestive enzymes into ducts.
  • Duct Cells
    Cells lining pancreatic ducts that secrete water and bicarbonate.
  • Head
    The round, medial end of the pancreas near the duodenum.
  • Body
    The middle section of the pancreas between the head and tail.
