Which would occur if the parasympathetic system were stimulated
Correct answer: B. Increase in digestion
- A. Increase in blood sugar
- B. Increase in digestion
- C. Increase in breathing rate
- D. Increase in adrenaline
Explanation
The parasympathetic nervous system predominates in quiet "rest and digest" conditions while the sympathetic nervous system drives the "fight or flight" response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
