During a "fight or flight" response, the adrenal medulla rapidly releases catecholamines into the bloodstream. Which of the following sets of physiological and metabolic changes is correctly associated with the action of these hormones?

Step-by-step solution

During a fight or flight response, the adrenal medulla secretes catecholamines (epinephrine and norepinephrine). These hormones prepare the body for emergency situations by inducing several physiological and metabolic changes. The physiological effects include increased alertness, pupillary dilation, piloerection (raising of hairs), profuse sweating, increased heart rate, increased strength of heart contraction, and an increased rate of respiration. The metabolic effects include the stimulation of glycogen breakdow
