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.) As the Clinton administration neared a nuclear deal with North Korea, it suspended the old, annual Team Spirit exercise that so irritated North Korea.
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.
Most commonly the term is applied to the internal surface of the stomach (gastric rugae). The function of the rugae is to allow the stomach, or other tissue, to expand when needed. When the stomach is not full, the rugae are folds in the tissue. However, as the stomach fills it expands by unfolding the rugae.
