Final answer:
The phases of Hans Selye's general adaptation syndrome are: A) Alarm, Resistance, and Exhaustion. These phases describe the body's responses from immediate reaction to prolonged stress and possible health consequences if the stress persists.
Step-by-step explanation:
The correct answer to the steps in the general adaptation syndrome, as described by Hans Selye, is A) Alarm, Resistance, Exhaustion. These stages represent the body's physiological reactions to stress over time and how it adapts and eventually may become depleted if stress is prolonged.
- The alarm reaction is the immediate response to a stressor, similar to the fight-or-flight response, involving a cascade of physiological reactions, including the release of hormones such as epinephrine and norepinephrine.
- The stage of resistance is where the body adapts to the stressor, with a continued state of alertness and preparation for response, though with less intensity than the initial alarm stage.
- Lastly, the stage of exhaustion occurs with prolonged stress exposure, which can lead to severe health problems like depression, immune suppression, and fatigue.
This process illustrates how stress affects the body through a predictable pattern over time, underscoring the importance of understanding and managing stress for maintaining good health.
