The lower esophageal sphincter prevents stomach acid from flowing back up into the esophagus, helping to prevent heartburn and acid reflux.
The four bodily sphincters are the: 1. lower esophageal sphincter, or cardiac sphincter (esophagus to the stomach)2. Pyloric sphincter (stomach to small intestines)3. Ileocecal sphincter or valve (small intestines to large intestines)4. Anal sphincter (rectum to outside)
The esophagus-stomach valve, also known as the lower esophageal sphincter, is a muscle that controls the flow of food and liquids from the esophagus into the stomach. Its main function is to prevent stomach contents from flowing back up into the esophagus, helping to prevent acid reflux and heartburn.
The esophagus is connected to the stomach through a muscular valve called the lower esophageal sphincter. This valve opens to allow food to pass from the esophagus into the stomach and then closes to prevent stomach contents from flowing back up into the esophagus.
The cecum and appendix in the digestive system serve as reservoirs for beneficial bacteria and aid in immune function.
A sphincter is a ring-like muscle that contracts and relaxes to control the flow of substances in and out of a body cavity. It acts as a valve to regulate the passage of food, liquids, and waste in various parts of the body, such as the digestive tract and urinary system.
The ring shaped muscle in the digestive system is the lower esophageal sphincter (LES).
The gastrointestinal tract contains sphincters, which are circular muscles that regulate the movement of material through the digestive system. Some examples of sphincters in the gastrointestinal tract include the lower esophageal sphincter, pyloric sphincter, and anal sphincter.

A rat's sphincter is a muscular ring that helps control the entry and exit of substances from its digestive system. It regulates the passage of food and waste materials through the digestive tract.

Bolus goes down esophagus, through lower esophageal sphincter (aka, cardiac sphincter) and into stomach. (A sphincter is a circular muscle which squeezes shut or opens the tubular digestive tract). It then passes through pyloric sphincter into small intestine. The small intestine is made up first of the duodenum, then jejunum, then ileum. From ileum, bolus goes to ascending colon, then transverse colon, then descending colon. From there to rectum and then out through anus (anal sphincter) .
1st: inferior esophageal sphincter (near esophagus passin through the diaphragm, prevents the reflux of gastric juices into the esophagus). 2nd: pyloric sphincter (at the pyloric part of stomach, controls the flow of contents from the stomach into the duodenum). 3rd: internal, external anal sphincter (lies in the anal canal and controls the discharge of wastes).
The pyloric sphincter regulates passage of chymefrom the stomach
the stomach
the function of organs in the digestive system is to break down food

If you're referring to sphincters "guarding" entrances and exits, it means that these specific muscles close the structure to prevent backflow of body fluid. Ex: there is a sphincter between the esophagus and the stomach that "guards" the entrance to prevent the very acidic gastric juice from entering the esophagus and damaging the lining. The muscles around the eye and mouth can also be considered sphincters.
