What is the Fight-or-Flight response?

• A. Buffers
• B. Fight-or-Flight
• C. Standards
• D. Accreditation

Answer: (B)

The Fight-or-Flight response is the body’s automatic, rapid reaction to a perceived threat. When danger is sensed, the brain signals the autonomic nervous system to activate the sympathetic branch, prompting the release of hormones like adrenaline and noradrenaline. These hormones cause quick changes: the heart rate and breathing speed up, blood is redirected to the muscles, pupils dilate, glucose is released for quick energy, and senses become sharpened. The purpose is to prepare you to either confront the threat or flee from it. That makes the term itself the best fit, because it’s the name of this specific physiological reaction. The other terms don’t describe a stress-response system—they refer to buffering chemicals, general guidelines, or formal certifications, which are unrelated to how the body responds to danger.
