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.
The gateway to your stomach is called the lower esophageal sphincter. This ring-like muscle opens and closes the passage between your esophagus and your stomach, as needed.
