North Korea has long complained about U.S.-South Korean military exercises â and not entirely without reason. (Ask a Georgian how Russiaâs Kavkaz-2008 exercise ended.)

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 is not the only part of your digestive system that absorbs food but rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of your intestines. The churning action of the stomach muscles physically breaks down the food. 2  The stomach releases acids and enzymes for the chemical breakdown of food. 3  The enzyme pepsin is responsible for protein breakdown. 4  The stomach releases food into the small intestine in a controlled and regulated manner.
