what are the three stages of general adaptation syndrome (GAS)
alarm stage, resistance, exhaustion or recovery
what happens during the alarm stage
the sympathetic nervous system kicks in and causes the fight or flight response

all changes are reversed and the person becomes less able to deal with the threat
alarm stage
what happens during the resistance stage
the parasympathetic nervous system kicks in and causes the body to calm down
what happens during the exhaustion or recovery stage
exhaustion occurs if the parasympathetic nervous system is unable to kick in, depleting energy
recovery occurs if the parasympathetic nervous system kicks in and there is effective coping

what is the inflammatory response
