Which digestive secretions functions as a chemical messenger?
hormones

How might stress affect the digestive system?
When stressed, the part of the brain(central nevous system)responsible for the stimulation of the digestive ezymes to perform their digestive functions,will feel too weak and stressed to perform its function of stimulating the ezymes thereby given rise to constipation.
What part of the autonomic nervous system causes an increase in digestive tract mobility?
Stimulation of the Parasympathetic nervous system causes an increase in digestive tract mobility. When stimulated the parasympathetic post-ganglionic neurons release a hormone called Acetylcholine. This causes the Digestive tract to increase its contractions. Counteracting this increase in digestive tract mobility is the sympathetic nervous system, which releases a hormone called noradrenaline which slows down the digestive tracts contractions. This is how the Parasympathetic Nervous System gets the name "rest and digest"
Which system is responsible for the formation of digestive enzymes?
digestive system.
Does sympathetic stimulation decrease the GI peristalsis?
yes. it inhibits your digestive tracts and digestion.
