The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. (However, this is considered a controversy because non-cellular life such as viruses are disputed as a life form. See Non-cellular life.)
Hydrochloric acid is the primary digestive acid and has several roles in digestion. The acid prevents harmful bacteria from entering your system by sterilizing it. Another function of hydrochloric acid is to trigger the release of pepsin. You need hydrochloric acid to absorb minerals like magnesium, sodium and iron. Gastric acid is so strong that it could digest the stomach if not for a mucus lining protecting the organ.
You can find a detailed list of foods and their pH values on the Center for Food Safety and Nutrition web site of the U.S. Food and Drug Administration (FDA). Gastric juice â the digestive liquids in your stomach â has a pH of 2.0, which is very, very acidic.The pH of hydrochloric acid is between 0.1 and 1.0 â probably the most acidic substance known to people. Eating acidic foods can't cause the stomach to become more acidic.n fact, during the process of digestion, the stomach secretes hydrochloric acid (HCl), a super-duper acidic substance that causes its contents to become acidic. Digestive enzymes, which begin their work in the stomach, require such an environment to function properly.
