Question

part b - lo 2, explain key stress theories as well as the emotional, mental, and physiological changes that occur during the stress response
homeostasis a balanced physiological state in which all the body’s systems function smoothly. stress threatens homeostasis, and the body attempts to return to normal through adaptive response.
choose the statement below that correctly describes a phase of the general adaptation syndrome (gas)

the body runs out of energy to make adjustments to the stressor and resistance drops to normal levels during the exhaustion phase.
the alarm phase of the gas triggers the flight-or-flight response, in which the body prepares to deal with a real or perceived threat.
during the alarm phase of the gas, epinephnne counteracts the effects of adrenaline.
during the resistance phase of the gas, the body resists the changes caused by the stressor and returns to homeostasis.

Explanation:

1. Analyze the first option: In the exhaustion phase, the body's resistance drops below normal, not to normal levels, so this is incorrect.
2. Analyze the second option: The alarm phase of GAS does trigger the fight - or - flight response, preparing the body for a real or perceived threat. This matches the definition of the alarm phase.
3. Analyze the third option: Epinephrine (adrenaline) and norepinephrine are part of the fight - or - flight response in the alarm phase, and epinephrine does not counteract adrenaline. So this is incorrect.
4. Analyze the fourth option: In the resistance phase, the body tries to resist the stressor, but if the stressor persists, it may move to exhaustion. It does not return to homeostasis in the resistance phase; homeostasis is restored if the stressor is removed, but the resistance phase is about resisting, not restoring to homeostasis.

Answer:

The alarm phase of the GAS triggers the flight - or - fight response, in which the body prepares to deal with a real or perceived threat.
