The stomach produces hydrochloric acid after a meal to aid in the digestion of food. The inner lining of the stomach resists corrosion by this acid. The cells lining the stomach secrete large amounts of protective mucus. The lining of the esophagus does not share these resistant features and stomach acid.
Your stomach, if you want to be technical about it, is a "crescent-shaped hollow organ" about the size of a large melon. The average adult stomach holds about three quarts (three liters) of fluid. Your stomach is made up of a variety of layers, including: Parietal cells produce hydrochloric acid, a
Mucous – Mucous (or mucus) is produced by cells in the mouth. esophagus, and stomach. It eases the passage of food through the gastrointestinal tract and protects the lining of the stomach from being attacked by acid. Neck cells also secrete bicarbonate, which buffers the acid and controls pH.
Parietal cells: secrete hydrochloric acid; Chief cells: secrete pepsin, a proteolytic enzyme; G cells: secrete the hormone gastrin; There are differences in the distribution of these cell types among regions of the stomach – for example, parietal cells are abundant in the glands of the body, but virtually absent in pyloric glands. The.
Equine Gastric Ulcer Syndrome in foals and horses results from a disequilibrium between mucosal aggressive factors (hydrochloric acid, pepsin, bile acids, organic acids) and mucosal protective factors (mucus, bicarbonate). Since mucosal protective factors are more developed in the glandular mucosa of the equine stomach when compared to the.
When hydrochloric acid passes from the stomach into the duodenum, secretin is released into the bloodstream and stimulates the duct cells of the pancreas to secrete water and bicarbonate. By this mechanism, hydrochloric acid secreted by the stomach, which can be damaging to the intestinal lining, is promptly diluted and neutralized.

The cells that line the stomach — called parietal cells — secrete hydrochloric acid or HCl, and this acid gives gastric juices their low pH. HCl does not digest food, but it kills bacteria, helps break down the connective tissue in meat, and activates pepsin, the stomach’s digestive enzyme.
Parietal cells (also called oxyntic cells) are the stomach epithelium cells which secrete gastric acid. Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via H2.
