Define a sphincter and describe the role of 2 different sphincters in the gastrointestinal tract.
(82) VerifiedA sphincter is a tight ring of muscle separating some of the organs of the gastrointestinal tract and opening in response to nerve signals indicating that food is ready to pass into the next section. Sphincters control the rate at which food flows from one organ to the next, and prevents backflows.
At the end of the esophagus is a sphincter muscle, the lower esophageal sphincter, or cardiac sphincter. This is normally tightly closed but when food reaches the end of the esophagus, this sphincter relaxes to allow the passage of very small amounts of food into the stomach.
The small intestine is composed of three sections. The duodenum is the section of the small intestine that is connected via the pyloric sphincter to the stomach. The jejunum is the middle portion, and the last portion is the ileum. It connects to the large intestine at another sphincter, called the ileocecal valve.
The large intestine is a thick, tubelike structure that frames the small intestine on three-and-a-half sides. It begins with a tissue sac called the cecum, which explains the name of the sphincter - the ileocecal valve - which connects it to the ileum of the small intestine.
