Definition of Pylorus:

The sphincter muscle at the distal (lower) opening of the stomach.  The pylorus only allows food to pass through after the digestive enzymes of the stomach have properly processed it.  Once through the pylorus on its way to the duodenum, the food is still only partially digested.
