Why does stress make your pupils dilate?
The sphincter papillae controls pupil constriction and is governed by the parasympathetic nervous system. The dilator papillae controls pupil dilation and is governed the sympathetic nervous system. During the fight or flight response, only the sympathetic nervous system is stimulated. With the massive amounts of noradrenaline flowing through this system, the dilator papillae is innervated and the pupils dilate.
What is the definition of fight or flight?
The "fight or flight" response is our body's primitive, automatic response that prepares the body to "fight" or "flee" from perceived attack, harm, or threat to survival.

The rate of respiration increases, blood is redirected from the digestive system into the muscles and limbs; which require extra energy for running and fighting, pupils dilate, awareness intensifies, sight sharpens, impulses quicken, perception of pain diminishes, and immune response intensifies.
What bodily changes are associated with the sympathetic nervous system's response during stress?
