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.
Parietal cells in the stomach secrete roughly two liters of acid a day in the form of hydrochloric acid. Acid in the stomach functions to kill bacteria, and to aid digestion by solubilizing food. The acid is also important to establish the optimal pH (between 1.8-3.5) for the function of the digestive enzyme pepsin.
