Alarm
When the body first reacts to a stressor, the sympathetic nervous system is activated.
Resistance
As the stress continues, the body settles into sympathetic division activity, continuing to release the stress hormones that help the body fight off, or resist, the stressor
Exhaustion
When the body’s resources are gone. It can lead to the formation of stress-related diseases or the death of the organism if outside help is unavailable.
Parasympathetic system
Returns the body to normal, day-to-day functioning after the stress is ended
Sympathetic system
Reacts when the human body is subjected to stress
