What term refers to the physiological and behavioral responses that aim to return the body to normal functioning, affecting multiple body systems?

• A. Stress response
• B. Stressor
• C. Fear
• D. Relaxation

Answer: (A)

The main idea is the body's stress response, a coordinated set of physiological and behavioral changes that work to restore normal functioning after a disturbance and involve multiple body systems. When an animal encounters a potential threat or challenge, the body activates systems across the nervous, endocrine, cardiovascular, and muscular domains, producing changes like quicker heart rate, faster breathing, and hormonal shifts, all aimed at returning to baseline once the situation is resolved. This makes the stress response the best term because it describes the whole regulatory process that seeks to reestablish homeostasis across many body systems, not just the trigger or the emotion behind it. A stressor is the thing that starts the response, fear is an emotion that can drive such responses but is not the process itself, and relaxation is the opposite of the stress response.
