Which of the following is not a part of the fight or flight response? adrenaline surges into the bloodstream

heart rate and blood pressure increases

pupils dilate

running away

pupils dilate. fight or flight is self explanatory ... you either stay and fight or run away ... when being attacked your body releases adrenaline, blood pressure and heart rate increase, or you could run away ... pupils dilating is NOT included.

The correct answer is pupil dilate.

Explanation:

During any stress condition adrenal gland release a hormone called adrenaline which is responsible for fight and flight response of the body. Due to the release of Adrenalin heart rate and breathing increase significantly for some time.

In this condition, the body decides whether to fight with the stress or to run away from there. This is a life-saving response in an acute stress condition.

Fight and flight response has no effect on pupil dilation rather pupil dilation is related to regulation of the intensity of light coming through eyes.
