Question

question 1-33
stress is the body and mind’s response to a stimulus. which of the following events occur during the body’s response known as “fight or flight”?

• increased heart rate, blood pressure, and respiration
• relaxation of the muscles
• a decrease in epinephrine levels
• decreased perspiration and blood pressure

Explanation:

The "fight or flight" response is part of the body's stress response, mediated by the sympathetic nervous system. During this response, the body prepares for action: heart rate, blood pressure, and respiration increase to supply more oxygen and energy to muscles. Muscles tense (not relax), epinephrine (adrenaline) levels increase (not decrease), and perspiration and blood pressure increase (not decrease). So the correct event is increased heart rate, blood pressure, and respiration.

Answer:

A. Increased heart rate, blood pressure, and respiration
