Question

which of the following is not a response to increased levels of parasympathetic activity?
a increased salivary secretions
b decreased metabolic rate
c decreased blood flow to the digestive tract
d decreased heart rate
e stimulation of urination

Explanation:

The parasympathetic nervous system is responsible for the "rest - and - digest" response. It increases salivary secretions (A), decreases metabolic rate (B), decreases heart rate (D), and stimulates urination (E). However, it increases blood flow to the digestive tract, not decreases it.

Answer:

C. decreased blood flow to the digestive tract
