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.
The stomach (from ancient Greek ÏÏÏÎ¼Î±ÏÎ¿Ï, stomachos, stoma means mouth) is a muscular, hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates. The stomach has a dilated structure and functions as a vital digestive organ.
