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.
The pyloric sphincter opens in response to the presence of acidic chyme in the stomach. This triggers hormonal and neural signals that stimulate the sphincter to relax and allow the chyme to pass into the small intestine. Once the chyme has been emptied, feedback mechanisms signal the pyloric sphincter to close to prevent backflow of contents into the stomach.
The pyloric sphincter opens in response to the presence of food in the stomach. This triggers a reflex that relaxes the sphincter, allowing food to pass into the small intestine. The sphincter closes to prevent the backflow of intestinal contents back into the stomach.
The pyloric sphincter opens in response to food entering the stomach. Stretch receptors in the stomach wall detect the food volume, signaling the sphincter to open and allow a controlled amount of chyme to pass into the small intestine for further digestion. Once the chyme has passed through, the sphincter closes to prevent backflow.
Sphincter of Oddi.
Incompetence of the esophageal sphincter is primarily characterized by gastroesophageal reflux disease (GERD). This condition occurs when the lower esophageal sphincter fails to close properly, allowing stomach acids to flow back into the esophagus, leading to symptoms such as heartburn, regurgitation, and difficulty swallowing. Other conditions associated with sphincter incompetence include hiatal hernia and esophagitis, which can exacerbate the reflux symptoms.

It is known as the lower esophageal sphincter or sometimes the cardioesophageal sphincter.
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
What is the function of the cardiac sphincter?
This depends on what sphnicter muscle you are talking about, because there is more than one sphincter muscle in a cow.

There are two sphincter muscles that "close" the rectum.
