*Anatomical terminology* [edit on Wikidata]

Centroacinar cells are spindle-shaped cells in the exocrine pancreas. Centroacinar cells are an extension of the intercalated duct cells into each pancreatic acinus.^[1] The intercalated ducts take the bicarbonate to intralobular ducts which become lobular ducts. These lobular ducts finally converge to form the main pancreatic duct.^[1]

These cells are commonly known as duct cells, and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin. They also secrete mucin.
