Which is true of the fight-or-flight response?

a. The sympathetic nervous system reverses the fight-or-flight response.
b. The parasympathetic nervous system induces the fight-or-flight response.
c. Prolonged responses lead to blood vessel constriction.
d. The fight-or-flight response creates more antibodies.

prolonged fight or flight response leads to blood vessel constriction. The correct option is C.

Explanation:

the sympathetic nervous system induces the fight-or-flight response through the sudden release of norepinephrine. This

can accelerate heart rate, widen bronchial passages, decrease motility of the large intestine, CONSTRICT BLOOD VESSELS, increase peristalsis in the esophagus, cause pupillary dilation, piloerection and perspiration (sweating), and raise blood pressure. Therefore, prolonged responses lead to blood vessel constriction.

The parasympathetic nervous system reverses the fight-or-flight response.
