Islets of Langerhans. The acini produce digestive enzymes. The islets produce hormones. The pancreas secretes digestive enzymes into the duodenum and hormones into the bloodstream.The digestive enzymes (such as amylase, lipase, and trypsin) are released from the cells of the acini and flow into the pancreatic duct.The pancreatic duct joins the common bile duct at the sphincter of Oddi, where both flow into the duodenum.
