Quizplus · Accepted Answer

The ileocecal valve is the sphincter that separates the small intestine from the large intestine. It regulates the flow of material from the small intestine into the large intestine, preventing backflow. The pyloric sphincter and lower esophageal sphincter are sphincters that regulate the flow of material in other parts of the digestive system. Bolus refers to a mass of partially digested food that has been formed into a rounded shape by the tongue and teeth in the mouth. The ileocecal valve is the circular muscle located at the junction of the small and large intestines that regulates the passage of material from the small intestine to the large intestine. The pyloric sphincter regulates the release of food from the stomach to the small intestine, while the lower esophageal sphincter prevents acid reflux and regurgitation from the stomach to the esophagus. Bolus refers to a mass of food that has been chewed and mixed with saliva in the mouth.
