Abnormal pancreas morphology Abnormal pancreatic acinus morphology 2023-02-21T01:07:32Z Structural anomal of pancreatic acinus. The exocrine pancreas is structurally analogous to a bunch of grapes; this architecture contains microscopic, blind-ended tubules that are surrounded by polygonal acinar cells and these tubules are organized into lobules called acini. The primary function of the acini is to synthesize and secrete hydrolytic enzymes which empty into the duodenum for the digestion of our daily foodstuff. Each acinus consists of a small cluster of secretory epithelial cells that form a small central lumen, called intercellular canaliculi. Each acinar cell has a round pyramid-like shape.
