Question

What regulates the exit of partially digested food from the stomach?

Answer 1

The exit of partially digested food from the stomach is regulated by the pyloric sphincter. The pylorus acts as a filter, allowing only liquids and small food particles to pass through into the small intestine. Rhythmic mixing waves force small amounts of chyme at a time through the pyloric sphincter and into the duodenum.

Step-by-step explanation:

The exit of partially digested food from the stomach is regulated by the pyloric sphincter. The pylorus acts as a filter, allowing only liquids and small food particles to pass through the mostly closed pyloric sphincter into the small intestine. Rhythmic mixing waves force small amounts of chyme at a time through the pyloric sphincter and into the duodenum, in a process called gastric emptying.

Answer 2

pyloric sphincter

Step-by-step explanation:

The upper and lower oesophageal sphincters. The lower sphincter, or cardiac sphincter, at the upper portion (cardia) of the stomach. This sphincter prevents the acidic contents of the stomach from moving upward into the esophagus. The pyloric sphincter, at the lower end of the stomach, regulates the exit of the partially digested food out of the stomach.
