Pancreatic cells. Coloured scanning electron micrograph (SEM) of acinar (exocrine) pancreatic cells. Acinar cells produce and excrete digestive enzymes to the small intestine, via the pancreatic ducts. The enzymes are excreted in vesicles known as zymogen granules (blue). The enzymes are activated in the small intestine and aid the breakdown of carbohydrates, fats and proteins. The proteins are produced, packaged and secreted by the cell's endoplasmic reticulum and golgi apparatus (orange strands). The cell nuclei (pink) are also visible.
