The ileocecal valve is a sphincter muscle and its function is to allow the passage of digested food frâ¦om the small intestine into the large intestine, as well as preventing the reflux of the contents of the large intestine back into the ileum (the last part of the small intestine).
The stomach 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.idges of muscle tissue called rugae line the stomach.
