The esophageal sphincter is a muscular ring at the junction of the esophagus and stomach. It helps prevent stomach acid and food from regurgitating back into the esophagus by contracting to close off the passage between the two organs. When we swallow, the sphincter relaxes to allow food to enter the stomach.
The lower esophageal sphincter keeps food from coming back up, or vomiting. When you have to vomit, the sphincter opens allowing the food to come back up. There is another sphincter, the pyloric sphincter which leads into the small intestine. Hope this helps!
The external anal sphincter is under voluntary control. You have the urge to defecate because your internal anal sphincter involuntarily opens, but you can keep yourself from going to the bathroom because your external anal sphincter is voluntarily closed. Hope that helps!
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)

What is the function of the cardiac sphincter?
No. The cardiac sphincter part of the stomach (also called the esophageal sphincter of the cardia) regulates how the food moves. This sphincter is close to the beginning of the stomach and it helps prevent gastric reflux back into the esophagus (GERD) or also called "heart burn". The contents of the stomach is a very strong acid.
The sphincter muscles close to prevent leakage of feces from the rectum and to maintain control over bowel movements. This helps in ensuring that waste is evacuated when you are ready to have a bowel movement.
