Fight-or-flight reactions cause activation of:

  1. A
    the parathyroid glands, leading to increased metabolic rate.
  2. B
    the kidney, leading to suppression of the RAAS pathway.
  3. C
    the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine.
  4. D
    the pancreas, leading to a reduction in blood sugar levels.
