<h2>Exhaustion stage of general adaptation.</h2>
Explanation:
The final stage of general adaptation theory is known as exhaustion stage.
The general adaptation is has been divided into three stages- Alarm stage, resistance stage and exhaustion stage.
The theory of adaptation describes the physiological changes that an organism undergoes when it is exposed to stress.
The first stage,which is the alarm stage which is characterized by the burst of energy and the stressor acts as a stimulus.
The second stage is the resistance stage when the organism develops the resistance against stressor.
The last stage is the exhaustion stage when the energy is sufficiently depleted and the final adjustment is attained.

The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.
