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.
After the stomach, food travels to the small intestine. The enzymes in the small intestine work best in alkaline conditions, but the food is acidic after being in the stomach. A substance called bile neutralises the acid to provide the alkaline conditions needed in the small intestine.Bile is produced by the liver and stored in the gall bladder.
