Increased Activity in the Sympathetic Nervous System Leads To

Question

Increased activity in the sympathetic nervous system leads to
A) decreased heart rate.
B) increased secretion by the pancreas.
C) increased secretion by the gallbladder.
D) increased contraction of the stomach.
E) relaxation of the airways in the lungs.

Accepted Answer

Increased activity in the sympathetic nervous system, often referred to as the "fight or flight" response, leads to physiological changes that prepare the body for rapid action. One such change is the relaxation of the airways in the lungs (bronchodilation), which is necessary to increase oxygen intake during times of stress or danger. This is why option E is correct. The other options describe effects that are not typically associated with increased sympathetic activity.
