The presence of hypertonic fluid in the small intestinal lumen initiates the enterogastric reflex, which inhibits stomach motility and emptying.

Question

The statement is correct. When hypertonic fluid (a fluid with a higher concentration of solutes than normal) is present in the small intestine, it triggers the enterogastric reflex. This reflex sends signals to the stomach to inhibit motility and prevent further emptying of chyme into the small intestine, allowing time for the hypertonic fluid to be diluted and properly digested.
