what is the stomach function
The stomach's main function is digestion. It does this by: The stomach uses pepsin (enzyme) and peptidase (another enzyme) to break down proteins in your food. The acid released by the stomach doesn't break down food it only provides a good environment for the enzymes to work in.o digest and store food until it is ready to go to the intestines In the frog, the function of the stomach is the same as in most vertebrates-to digest proteins and mechani â¦ cally break larger food particles down into smaller and more liquid particles that can be digested by the small intestine.
