Stomach enzymes are found in digestive juices created by cells in the stomach.
These juices also contain a very strong acid. The enzymes in the stomach work best in the acid. The acid kills the harmful bacteria that may be present in some
materials that enter the stomach. The
stomach is protected from the acid by a special lining. From the stomach, food passes through to the small intestine.
Even though food never actually enters
the liver, the liver still plays an important
part in digestion. The liver secretes certain
digestive fluids that reach food as it enters
the small intestine.
