MEDICAL PHYSIOLOGY

Detailed explanation-1: -Passing stool immediately after a meal is usually the result of the gastrocolic reflex, which is a normal bodily reaction to food entering the stomach. Almost everyone will experience the effects of the gastrocolic reflex from time to time. However, its intensity can vary from person to person.

Detailed explanation-2: -It may feel as if “food goes right through them, ‘’ and it can be accompanied by pain, cramping, diarrhea, or constipation. That exaggerated gastrocolic reflex isn’t a condition in itself. It’s typically a symptom of irritable bowel syndrome (IBS) in adults. In infants, it’s completely normal.

Detailed explanation-3: -The rectoanal inhibitory reflex (RAIR) (also known as the anal sampling mechanism, anal sampling reflex, rectosphincteric reflex, or anorectal sampling reflex) is a reflex characterized by a transient involuntary relaxation of the internal anal sphincter in response to distention of the rectum.
