The pyloric sphincter (valve), located at the base of the stomach, relaxes causing
a small quantity of chyme to pass through the opening into the first part of the
small intestine.
This initiates a reflex that causes the muscles of the sphincter to contract and
close the opening temporarily. Then the sphincter relaxes again and allows more
chyme to enter.
