The stomach is a muscular sac that lies between the esophagus and the small intestine in the upper abdomen. Hydrogen ions are moved through the membrane of a parietal cell and into the duct of a gastric gland by a proton pump known as … It can also keep food from fermenting in the recesses of the stomach, vital to preventing food poisoning. and Not to mention depleting the body of vital nutrients. Pepsin is an active enzyme that helps in the digestion of protein by breaking it into its simpler unit’s peptides and amino acids. . They contain an extensive secretory network of canaliculi from which the HCl is secreted by active transport into the stomach. Hydrochloric acid dissolves bits of food and creates an acidic medium. Its important to mention that HCL production is a major expenditure of biological energy. The stomach is where chemical digestion mainly happens, especially that of protein. Bile juice also helps in the absorption of fats. Gastric glands are present in the wall of the stomach which secrete gastric juice containing the digestive enzyme like pepsin, renin, mucus and HCl. The acid is made by parietal cells in the gastric glands of the stomach lining. Other cells in the lining of your stomach, called chief cells, secrete other important substances, one of which is called pepsinogen. It then travels through your esophagus and into your stomach, where it's mixed with gastric juices that contain a large percentage of hydrochloric acid, also called HCl, stomach acid or gastric acid. Leaf Group Ltd. This article will outline the production of stomach acid, the regulation of this and some clinical conditions that result from this process going wrong. It is also known as Muriatic Acid and spirits of salt or acidum salis. The role of gastric acid in digestion was established in the 1820s and 1830s by William Beaumont on Alexis St. Martin, who, as a result of an accident, had a fistula (hole) in his stomach, which allowed Beaumont to observe the process of digestion and to extract gastric acid, verifying that acid played a crucial role in digestion. *HCl along with gastric lipase emulsifies the lipids present in our food. The stomach has a muscular folded tissue contains gastric glands which secret pepsin, HCl, and mucus. Stomach mucus protects the gastrointestinal cells from the damage that gastric juices can cause. *This provides an acidic environment for many digestive enzymes to become active. It activates trypsinogen into trypsin.

The pH level in the stomach ranges from 1.5 to 3, depending on factors such as food intake, stress, and medications or supplements. An important function of HCl in the stomach is protein breakdown. Each organ has a separate job and relies on a series of processes to complete its job. This concentrated HCl is secreted by the oxyntic cells. Pepsin is classified as a protease enzyme because it helps break apart the protein from the food you eat into its smaller components, called amino acids. Privacy Policy It kills the germs, microbes and pathogens that enter the stomach. Yes, magnesium because this mineral participates in the production of stomach acid too.Disclaimer (b) Secretion of mucus for the protection of inner lining of the stomach. It maintains a PH in the stomach. • Mucus from the mucus gland protect the epithelium lining of the stomach from the action of HCL. Because hydrochloric acid is such a vital component in nutrient digestion and absorption, people who take proton-pump inhibitors, or medications that reduce the production of stomach acid, have a higher risk of developing vitamin and mineral deficiencies than people who don't. Without adequate HCL in the stomach your body has no choice but to hold your food in your stomach until it naturally begins to break down through fermentation or rotting in order to move on to the next phase. 11. Following are the roles it plays in digestion: A. Denaturation of protein: Acid cause loosening of the highly folded structure of a protein. Its role is to create an acidic medium in the stomach so that other enzymes and gastric juices could do their work well.
