sympathoadrenal discharge
the sympathoadrenal system can discharge as one unit and prepare the animal in all systems for immediate fight or flight. There is an increase in heart rate, ventricular contractile strength, cardiac output, blood pressure plus pupillary dilatation, increased respiratory rate, bronchiolar dilatation, diversion of blood flow from the splanchnic to skeletal muscle circulation and elevation of the blood sugar.
