When the client's ileum becomes distended, the nurse knows that the ileogastric reflex will inhibit gastric motility. When the ileum becomes distended, the ileogastric reflex will also prevent chyme from continuing to move into the intestines. Chyme is an acidic mixture of gastric juices and partly digested food that passes from the stomach to the intestines, but it will be inhibited from its movement by the ileogastric reflex when the intestines are already distended.
