You are living in a place that experiences wildfires annually. This year, in particular, has had multiple weeks of high-intensity fires. Which physiological system is likely activated in this situation?

• B. Sympathetic Nervous System.

• D. Parasympathetic Nervous System.

Answer: (A)

Verified step by step guidance

1. Identify the context of the problem: The scenario involves a stressful situation due to the presence of wildfires.
2. Understand the physiological systems involved in stress response: The body has several systems that respond to stress, including the HPA Axis and the Sympathetic Nervous System.
3. Consider the role of the HPA Axis: The Hypothalamic-Pituitary-Adrenal (HPA) Axis is a central stress response system that releases cortisol, a hormone that helps the body manage stress.
4. Consider the role of the Sympathetic Nervous System: This system is part of the autonomic nervous system and is responsible for the 'fight or flight' response, increasing heart rate and energy availability.
5. Evaluate which system is most likely activated: In a high-stress situation like wildfires, both the HPA Axis and the Sympathetic Nervous System are likely activated, but the immediate response is typically associated with the Sympathetic Nervous System.
