Pancreatic tissue. Scanning electron micrograph (SEM) of a freeze fractured pancreas. The pancreas gland shows numerous acinar cells, containing small round secretory zymogen granules. Digestive enzymes are secreted in the zymogen granules, and passed to the small intestine through the pancreatic ducts. Golgi and endoplasmic reticulum as well as several nuclei are visible. A central capillary containing a single red blood cell is also present. Magnification: x2500 when printed at 10cm
