Document Summary
Glucocorticoids (whole class of stress related hormones, ex: cortisol) Reduce parasympathetic nervous system activity (parasympathetic = resting and relaxing, in charge of all high energy activity that aren"t immediately necessary, ex: growth and repair)(activate sympathetic will reduce parasympathetic nervous syst) Increases heart rate and blood pressure (to get more nutrients and o2 to exercising muscles) Enhance effects of epinephrine and norepinephrine on heart muscle (medulla oblongata) Blood entering heart with more force (it"s entering our heart with more force) Heart walls snap back with more force. Divert blood away from nonessential parts of the body (and bring to places that. Increase in blood pressure (by constricting blood vessels are essential) Vasopressin = prevent urine formation (released during stress response) Expel dead weight in bladder (our bladder is full of dead weight, if we expel our bladder we"re lighter and can move effectively) If we overpump it, it causes wear and tear.
