Note the washed out cytoplasm and flat nuclei of the mucous secreting cells compared to the basophilic (purple) cytoplasm and round nuclei of the serous secreting cells.
This is a section of the pancreas. ID the gland by the product secreted. Glandular cells are outlined.
The cells outlined have round nuclei with the nuclei located at the base of the cell while the secretory granules are apically located. These cells will secrete apically releasing their granular contents into a duct (exocrine secretion). The round nuclei is consistent with serous glands. No lipid secreting cells in the field of view.
