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.
