Acinar cells. 1  Acinar cells are the exocrine (exo=outward) cells of the pancreas that produce and transport enzymes that are passed into the duodenum where they assist in the digestion of food.
Within the pancreas, acinar cells produce the digestion enzymes, which travel in pancreatic juice into the duodenum through a system of ducts (which produce the pancreatic juice).Many of the pancreatic enzymes are actually proto-enzymes; they require another chemical in the duodenum to transform into an actual enzyme.ithin the pancreas, acinar cells produce the digestion enzymes, which travel in pancreatic juice into the duodenum through a system of ducts (which produce the pancreatic juice).
