The document summarizes the structure and function of the stomach and intestines. The stomach breaks down food, stores it, and slowly empties into the small intestine. The small intestine further breaks down food with help from the pancreas, liver, and gallbladder. The large intestine absorbs water from undigested material and passes waste. Common ailments include indigestion, diarrhea, and constipation. Proper diet, hydration, chewing, eating habits, and bowel regularity help maintain stomach health.
