The stomach plays a major role in digestion, both in a mechanical sense by mixing and crushing the food, and also in an enzymatic sense, by digesting it.
Digestive enzymes are necessary to breakdown and digest foods so that they can be absorbed. They need the right amount of acid in the stomach, the right amount of alkali in the duodenum, and the right amount of time spent in each department so that these enzymes can work.he best known is lactase, which is the enzyme necessary to digest milk sugar.
