Gastric juicy are very much acidic and, without this mucus, the acidity can certainly demolish the cellular material and cells in the digestive system. Lipids, sugars, certain amino acids, and nutrients of high osmolality trigger sensory mechanisms from the intestine which inhibit gastric emptying. Gastric juices functions the body to absorb each efficient particle properly: The instinctive element in gastric juices enables the body system to soak up B-12, an essential nutritional for neurological system function along with the development of blood tissues. For acidifying stomach content Hydrochloric acid is the main component of the gastric juices produced in the stomach and it maintains the stomach pH of 1 to 2 by acidifying the stomach contents.
