What happens when the sympathetic branch becomes active during the fight-or-flight response?
What will be an ideal response?
Sympathetic branch activation during the fight-or-flight response results in increased dilation of the pupils for maximal visual access to threatening stimuli. Interestingly, our eyes also dilate when we see pleasurable stimuli, like potential mates, perhaps to also maximize visual access, though for obviously different reasons. The lungs experience bronchial dilation to maximize oxygen input into the bloodstream. The heart rate and stroke volume (the amount of blood ejected during the heart's contraction) increase while the blood vessels constrict which has the net effect of cranking up the body's blood pressure to move blood more rapidly through the system so that it can more quickly oxygenate and fuel the brain and large muscles of the body.
