Key Stage 1
Meaning
The stomach is a part of the body where our food goes when we eat it.
Key Stage 2

About the Stomach
- The stomach produces Hydrochloric Acid.
- The Hydrochloric Acid in the stomach kills bacteria to help prevent us getting sick.
- The stomach digests food using enzymes.
- The enzymes in the stomach work best in acid.
Key Stage 4
Meaning
The stomach is an organ in the digestive system which breaks down food molecules into small molecules using enzymes.
About the Stomach
- The stomach produces Hydrochloric Acid.
- The stomach digests food using digestive enzymes including a protease called pepsin which breaks down proteins into amino acids.
- The Hydrochloric Acid in the stomach kills bacteria to help prevent infection and keeps the stomach acidic to be the optimum pH for the Digestive Enzymes to work.
- The protease pepsin is an enzyme found in the stomach which has an optimum pH of 1.6.
