How does acetylcholine influence chemical and physical digestion?


1.Chemical—triggers release of pancreatic enzyme; Physical—triggers stomach muscle contraction

2. Chemical—triggers release of bile; Physical—triggers tongue contraction

3.Chemical—triggers stomach muscle contraction; Physical—triggers release of pancreatic enzyme

4. Chemical—triggers tongue contraction; Physical—triggers release of bile (This answer choice is WRONG)

Respuesta :

The answer seems to be: 1.Chemical—triggers release of pancreatic enzyme; Physical—triggers stomach muscle contraction. The second choice is wrong since acetylcholine does not directly influence tongue contraction. The third choice is wrong because of the part "Physical—triggers release of pancreatic enzyme"
