Enteroendocrine cell Enteroendocrine cells are located in the stomach, in the intestine and in the pancreas.hey produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses.

- Intrinsic factor is a protein produced by the cells of the stomach, parietal cells, which also produce the acid (gastric juice) for digestion.The intrinsic factor is the compound which facilitates and allows the absorption of vitamin B12 from food in the stomach and the intestines.ntrinsic factor is a protein produced by the cells of the stomach, parietal cells, which also produce the acid (gastric juice) for digestion.

- From Wikipedia, the free encyclopedia. Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.astrin binds to cholecystokinin B receptors to stimulate the release of histamines in enterochromaffin-like cells, and it induces the insertion of K + /H + ATPase pumps into the apical membrane of parietal cells (which in turn increases H + release into the stomach cavity).

Pepsinogen Pepsin is expressed as a pro-form zymogen, pepsinogen, whose primary structure has an additional 44 amino acids. In the stomach, chief cells release pepsinogen. This zymogen is activated by hydrochloric acid (HCl), which is released from parietal cells in the stomach lining.The hormone gastrin and the vagus nerve trigger the release of both pepsinogen and HCl from the stomach lining when food is ingested.epsin is expressed as a pro-form zymogen, pepsinogen, whose primary structure has an additional 44 amino acids.

Digestive enzyme Digestive enzymes are secreted by different exocrine glands including: 1  Salivary glands. 2  Secretory cells in the stomach. 3  Secretory cells in the pancreas. 4  Secretory glands in the small intestine. It is produced by the stomach cells called chief cells in its inactive form pepsinogen, which is a zymogen. 2  Pepsinogen is then activated by the stomach acid into its active form, pepsin. 3  Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids.

Gastric mucosa Enterochromaffin-like cells (ECLs), found in the oxyntic glands release histamine, which also is a powerful stimulant of the acid secretion. The A cells produce glucagon, which mobilizes the hepatic glycogen, and the enterochromaffin cells produce serotonin, which stimulates the contraction of the smooth muscles.

- The stomach cells also produce a protein called intrinsic factor (IF), which travels to the small intestine. When the corrinoid-R-protein complex gets to the small intestine, the corrinoid is liberated from the R-protein by enzymes made by the pancreas (3).n animals, B12 is normally attached to a protein either for transport or storage. When humans eat animal foods, the B12 is protein-bound. When the protein-B12 complex reaches the stomach, the stomach secretes acids and enzymes that detach the B12 from the protein.

Parietal cell Parietal cells also produce intrinsic factor. Intrinsic factor is required for the absorption of Vitamin B12 in the diet. A long-term deficiency in vitamin B 12 can lead to megaloblastic anemia, characterized by large fragile erythrocytes.arietal cells (also known as oxyntic or delomorphous cells), are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and in the body of the stomach.

- The newly arrived chyme also stimulates enteroendocrine cells of the intestine to release compounds that stimulate the pancreas and gall bladder, while also suppressing gastric secretion and motility to allow the duodenum to process the chyme before receiving more from the stomach.

- The stomach produces and secretes several important substances to control the digestion of food. Each of these substances is produced by exocrine or endocrine cells found in the mucosa. The main exocrine product of the stomach is gastric juice – a mixture of mucus, hydrochloric acid, and digestive enzymes.

- Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides.epsin is expressed as a pro-form zymogen, pepsinogen, whose primary structure has an additional 44 amino acids. In the stomach, chief cells release pepsinogen.

The Two Types of Exocrine Secretory Cells in the Stomach The stomach is an organ of the digestive system. The inner wall of the stomach contains small pores called gastric pits. These pits contain cells that secrete chemicals that digest food. The two main types of exocrine secretory cells of the stomach are parietal cells and chief cells.Parietal cells secrete hydrochloric acid and chief cells secrete digestive enzymes such as pepsin. These cells secrete their products when activated by signals from the body such as hormones and neurotransmitters.hese pits contain cells that secrete chemicals that digest food.

What Are Enteroendocrine Cells? Enteroendocrine cells are those endocrine cells found int eh gastrointestinal tract. Enteroendocrine cells are present in the stomach and intestines. The endocrine system produces signaling chemicals for specific internal parts of the body.

Chief cell Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells. This type of cell also secretes gastric lipase enzymes, which help digest triglycerides into free fatty acids and di-and mono-glycerides.epsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells.

Why Inhibiting Acid Production With Prilosec and Prevacid Could Make Ulcers Worse Inflammation of the stomach lining coincides with production of peptides called cytokines, which stimulate production of a hormone called gastrin. Gastrin triggers parietal cells in the stomach lining to produce more hydrochloric acid, which kills off most invading microbes.

- Another population of chromaffin cells is found only in the stomach wall, called enterochromaffin-like cells (ECL). They look like EC cells but do not contain 5-HT. ECL cells respond to gastrin released by G-cells and they release histamine, which will stimulate the parietal cells to produce gastric acid.
