Stomach Function: Digestion, Protection & Key Roles

The main functions of the stomach are to:

- Store ingested food and liquids and release it into the small intestine in a regulated manner.

- Break down food and begin the process of digestion, preparing it for further breakdown and absorption in the small intestine.

- Protect the body from harmful bacteria and toxins in food through its stomach acid and protective mucus lining.

- Produce hormones that regulate appetite and digestion, such as ghrelin and gastrin.

- Assist in the absorption of certain nutrients, such as iron and calcium.
