AAbout 1 to 2 hours
BAbout 6 to 8 hours
CAbout 3 to 4 hours
DAbout 12 to 24 hours
Answer & Solution
Correct answer: C. About 3 to 4 hours
1. Gastric secretion runs in three phases named for where the trigger comes from: cephalic, gastric and intestinal.
2. The cephalic phase is brief and starts before food arrives, on the smell, taste, sight or thought of food.
3. The gastric phase is set off by food entering the stomach and lasts 3 to 4 hours.
4. Twelve to 24 hours is how long residue lingers in the large intestine, a different measurement entirely.
