Fight - or - flight reaction cause activation of:

1.	the parathyroid glands, leading to increased metabolic rate.
2.	the kidney, leading to suppression of the rennin angiotensin-aldosterone pathway.
3.	the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine
4.	the pancreas leading to a reduction in blood sugar levels.
