The area of the stomach that acts as a temporary storage area is the "fundic".
Four main parts of the stomach:
1. Cardiac (esophageal opening, cardiac sphincter)
2. Fundic (temporary storage area, lies slightly above the cardiac region)
3. Body (central area of the stomach)
5. Pyloric (pyloric sphincter, controls emptying of the stomach into the sm. Intestine)
The stomach is a muscular organ located on the left side of the upper abdomen. It receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.
The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
