The mucosa contains specialized cells and glands that produce hydrochloric acid and digestive enzymes to help digest food. The mucosa in the cardiac and pyloric regions of the stomach release mucus that helps protect the lining of the stomach from the acid produced for digestion.Click to see full answer. Also, how are cells in the digestive system specialized?Absorptive cells, or enterocytes, are the predominant epithelial cell type lining the lumen of the small intestine and colon. These cells are specialized for absorption of nutrients across the apical plasma membrane and export of these same nutrients across the basal plasma membrane.One may also ask, what are 4 cells of the stomach and their function? Four major types of secretory epithelial cells cover the surface of the stomach and extend down into gastric pits and glands: Mucous cells: secrete an alkaline mucus that protects the epithelium against shear stress and acid. Parietal cells: secrete hydrochloric acid. Chief cells: secrete pepsin, a proteolytic enzyme. Keeping this in view, what type of cells line the stomach? The lining epithelium of the stomach, and gastric pits is entirely made up of mucous columnar cells. These cells produce a thick coating of mucus, that protects the gastric mucosa from acid and enzymes in the lumen.What do chief cells do in the stomach?The gastric chief cell (also known as a zymogenic cell or peptic cell) is a cell 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.
