Final answer:
Gastric emptying is the process by which chyme is released into the duodenum. It is regulated by both the stomach and the duodenum. Rhythmic mixing waves force small amounts of chyme at a time through the pyloric sphincter.
Step-by-step explanation:
The process of gastric emptying involves the release of chyme into the duodenum. This process is regulated by both the stomach and the duodenum.
Rhythmic mixing waves force small amounts of chyme at a time through the pyloric sphincter and into the duodenum. This prevents overwhelming the capacity of the small intestine.
