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.
There are three specific conditions that allow bacteria to survive through the harsh acidic conditions of the stomach: bacteria can be protected from low pH by binding to food constituents, [26] usage of antacids or acid blockers would also substantially increase the chances of gastric survival and influence subsequent infection by increasing the stomach pH, [27] and [babies] produce lower levels of acid in their stomach allowing spores to survive through the stomach [28].
