Your stomach is where the food you eat is broken
down into smaller pieces. This action is called digestion.
Stomach (gastric) juice is the term used to describe the chemicals that
break down food in the stomach. These include hydrochloric acid and an enzyme
called pepsin. Gastric juice is sometimes referred to as stomach acid, although
not all of the substances in gastric juice are acidic.
