What controls the passage of chyme from the last region of the stomach to the duodenum region of the small intestine?

The correct answer is PHYLORIC SHPINCTER.

Explanation:

The partially digested food material that is usually find in the stomach during the digestion process is called chyme. In the stomach, the digestion process include the secretion of hydrochloric acid and some enzymes, which break down the food molecules. The muscular wall of the stomach helps in the digestion process by churning up the food. The resulting partially digested food is called chyme.

When the digestion process in the stomach is over, the chyme usually move to the duodenum through a valve known as the phyloric spincter.
