MEDICAL PHYSIOLOGY

Detailed explanation-1: -After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.

Detailed explanation-2: -Most patients have a small-bowel transit time of between 30 min and 3 hr. The minor-ity of cases, in which the small-bowel transit time lies outside of this range, should not ab-solutely be diagnosed as abnormal without correlation with associated radiographic and clinical findings.

Detailed explanation-3: -Transit time is the duration between when you take a bite of your meal and when leftover waste finally passes out as stool (feces). A meal could take anywhere from 12-72 hours to travel through the digestive tract.

Detailed explanation-4: -The duration the food particles take to reach the stomach depends upon the nature of the food. If it’s liquid food, it takes only 1-2 seconds to reach the stomach whereas semisolid food takes 4-6 seconds. Solid foods take up to 7-8 seconds to reach the stomach for digestion.
