<P> The pancreas is a secretory structure with an internal hormonal role ( endocrine ) and an external digestive role ( exocrine ) . The endocrine part is composed of hormonal tissue distributed along the pancreas in discrete units called islets of Langerhans . Islets of Langerhans have a well - established structure and form density routes through the exocrine tissue . The exocrine part has two main ducts , the main pancreatic duct , and the accessory pancreatic duct . These drain enzymes through the ampulla of Vater into the duodenum . </P>
