When the stomach fills, reflexes coordinate how fast contents move through the digestive tract. The two that speed transit through the small intestine are the gastroenteric reflex and the gastroileal reflex. The gastroenteric reflex increases small-intestine motility in response to gastric distension, pushing chyme along the small intestine. The gastroileal reflex, also triggered by a full stomach, enhances ileal peristalsis and relaxes the ileocecal sphincter to move contents into the large intestine, effectively speeding throughput from the ileum onward. Other reflexes either slow stomach activity (enterogastric), boost colonic activity (gastrocolic), or involve the ileum affecting the stomach (ileogastric), not accelerating small-intestine transit.
