Pancreas Acini of the exocrine pancreas demonstrate the polarity of exocrine secretory cells Rough endoplasmic reticulum is evident at the periphery of each acinar cell;As in salivary glands, intercalated ductal cells in the pancreas contribute bicarbonate ions (sodium and water follow passively) to the exocrine secretory product However, unlike salivary glands, there are no striated ducts in the pancreas to recover sodium, so the final product is rich in both sodium and bicarbonate (as opposed to saliva in which the sodium content is about one tenthThe endocrine pancreas that secretes insulin and glucogon is more lightly stained and its cells cluster to form the Islets of Langerhans The rest of the image consists of the exocrine pancreas that produces several enzymes critical for digestion and adsorption of food Note how the cells of the exocrine pancreas form small clusters or acini

 The pancreas is a twoheaded organ, not only in origin but also in function In origin, the pancreas develops from two separate primordia In function, the organ has both endocrine function in relation to regulating blood glucose (and also other hormone secretions) and gastrointestinal function as an exocrine (digestive) organ, see exocrine pancreas Exocrine vs Endocrine Fundamentally, the difference between exocrine and endocrine is exocrine secretes (via ducts) to an external surface or body cavity endocrine secretes within an enclosed system eg the bloodstream As the acini of the pancreas secrete into a network of ducts, this gives this organ an exocrine functionDescribe the endocrine function of the pancreas involves the release of hormones that regulate carbohydrate metabolism;

The pancreas contains two sets of cells exocrine cells that secrete enzymes via ducts into the intestine, and endocrine cells that secrete hormones into the bloodstream The exocrine cells are small and arranged in spherical secretory units called acini On a slide, one acinus would look something like a pie cut into several pieces4 rows  The pancreas is both an exocrine accessory digestive organ and a hormone secreting endocrineIn humans, it is located in the abdomen behind the stomach and functions as a gland The pancreas has both an endocrine and a digestive exocrine function As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin, and pancreatic polypeptide

The pancreas is an organ containing two distinct populations of cells, the exocrine cells that secrete enzymes into the digestive tract, and the endocrine cells that secrete hormones into the bloodstream It arises from the endoderm as a dorsal and a ventral bud which fuse together to form the single organSecretory granules are located at the apex, adjacent to the lumen into which their contents will be released Centroacinar cells, located in the center of each acinus, form the beginning of the intralobular duct systemQualitative assessment of the number of islets of Langerhans and the degrees of exocrine pancreatic atrophy, fibrosis, and fat replacement was made for each pancreas Quantitative assessment of islet composition was performed in 15 of the 17 based on the immunochemical reactivity of each cell type Nondiabetic patients with cystic fibrosis in
