Cells
Parietal cells- secrete hydrochloric acid (HCl) and intrinsic factor. These are among the most dramatically differentiated epithelial cells in the body, with functional specialization reflected in their microscopic appearance. These cells are located in the gastric glands found in the lining of the fundus and in the body of the stomach. relatively large cells, with one or two oval, centrally located euchromatic nuclei. The cytoplasm is strongly acidophilic, is somewhat grainy in appearance, and is typically less-intensely stained in a "halo" zone midway between the nucleus and the cell membrane. This cytoplasmic appearance is closely associated with the parietal cell's functional specialization for secreting acid.

Gastric chief cells- cells in the stomach that releases pepsinogen and chymosin. Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells.
G cells- a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum.
Delta (D) cells- somatostatin-producing cells. They can be found in the stomach, intestine and the Islets of Langerhans in the pancreas.
Goblet cells- scattered among the absorptive cells in the epithelium of the small intestine and colon. These epithelial cells are specialized for secretion of mucus, which facilitates passage of material through the bowel. The name "goblet" refers to the cell's shape, narrow at the base and bulging apically.
