Transit Time
The time taken for food or other ingested objects to transit through the gastrointestinal tract varies depending on many factors, but roughly, it takes 2.5 to 3 hours after a meal for 50% of stomach contents to empty into the intestines and total emptying of the stomach takes 4 to 5 hours. Subsequently, 50% emptying of the small intestine takes 2.5 to 3 hours. Finally, transit through the colon takes 30 to 40 hours.

Famous quotes containing the words transit and/or time:
“My esoteric doctrine, is that if you entertain any doubt, it is safest to take the unpopular side in the first instance. Transit from the unpopular, is easy ... but from the popular to the unpopular is so steep and rugged that it is impossible to maintain it.”
—William Lamb Melbourne, 2nd Viscount (1779–1848)
“... the time will come when no servant will be hired without a diploma from some training school, and a girl will as much expect to fit herself for house-maid or cook, as for dressmaker or any trade.”
—Lydia Hoyt Farmer (1842–1903)
