The phyloric sphincter is at the bottom of your stomach. It is the opening to the jejunum (the beginning of the small intestines).
The orifice is an opening such as the nostrils, mouth, etc. The sphincter is a muscle. These are like valves that only allow certain materials to go in and out and are often very tight, resulting in the action of peristalsis.
The sphincter of Oddi regulates the passage of pancreatic juices and bile into the duodenum of the small intestine.
The Lower Esophageal Sphincter.
There s the sphincter around the opening of the bladder.
The opening between the stomach and the small intestine is called the Pyloric Sphincter- it is a ring of muscle that contracts when the stomach is full, to seal off the opening to the small intestine whilst foodstuffs are liquified in the stomach. When this has been done, the sphincter muscle relaxes, re-opening the channel to allow the liquified nutrients into the intestines.

a ring of muscle that controls the release of an organs products. EXAMPLE: Pyloric Sphincter controls release of chyme. Cardiac Sphincter controls deposition of food into the stomach from the esophagus. External Urethral Sphincter controls release of urine. External Anal Sphincter controls release of defecation.
There are two openings in the stomach. The first opening is the esophageal sphincter, and the second is the Pyloric sphincter.

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