Welcome: to your body. The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus from your mouth. This is where a major part of digestion of food occurs. The stomach secretes acid and enzymes that digest the food. Ridges of muscle tissue called rugae line the stomach. The rugae contract periodically churning food. Growling may mean hunger.
