Compound acinar gland
This electron micrograph shows an acinus from a compound acinar gland. These highly polarized cells show prominent, basally located RER and numerous apical secretory granules. The granules contain digestive enzymes which are secreted by the merocrine mode of secretion into the central lumen of the acinus. Pancreas 3000x
