[5] With a pH of approximately 2, chyme emerging from the stomach is very acidic. [6]
Transit time through the small intestine is an average of 4 hours. Half of the food residues of a meal have emptied from the small intestine by an average of 5.4 hours after ingestion. Emptying of the small intestine is complete after an average of 8.6 hours. [30]
