Final answer:
The general adaptation syndrome (GAS) model proposed by Dr. Hans Selye explains the body's physiological reactions to stress. It consists of three stages: alarm reaction, stage of resistance, and stage of exhaustion.
Step-by-step explanation:
The general adaptation syndrome (GAS) model, proposed by Dr. Hans Selye, explains the body's physiological reactions to stress and the process of stress adaptation.
t consists of three stages: alarm reaction, stage of resistance, and stage of exhaustion. The alarm reaction is the immediate response to a threatening situation, similar to the fight-or-flight response.
The stage of resistance is when the body adapts to the stressor and tries to restore balance. Finally, the stage of exhaustion occurs when the body's resources are depleted, which can lead to serious health problems.
