Secretory granules
This electron micrograph of a pancreatic acinus shows secretory granules in the apex of each cell and the RER and nucleus at the base. These secretory granules contain digestive enzymes, and thus, are referred to as zymogen granules. The contents of these granules are released by exocytosis into the lumen at the center of the acinus. 4000x
