Bowel transit time

Bowel transit time refers to how long it takes for the food to move from the mouth to the end of the intestine (anus).

This article talks about the medical test used to determine bowel transit time using a radiopaque marker testing.

Lower digestive anatomy

Food passes from the stomach into the small intestine. In the small intestine all nutrient absorption occurs. Whatever has not been absorbed by the small intestine passes into the colon. In the colon most of the water is absorbed from the food residue. The residue is then eliminated from the body as feces.
