When exposed to life-threatening stress, your body naturally moves blood to certain muscle groups, causing which of the following?

Explanation:
When life gets life-threatening, the body switches into fight-or-flight. Blood is redirected toward the muscles you’d use to move fast or fight, while less blood goes to peripheral areas like the eyes. That shift can narrow your visual field, so you experience tunnel vision—your awareness focuses on a central area as you try to react to the threat. This is a protective response that helps you concentrate on what's directly in front of you. Auditory exclusion is another stress response you might hear about, where hearing becomes less acute, but it’s not the visual narrowing described by the blood-flow shift to muscles. Space condensing isn’t a recognized physiological term here, and time perception changes can occur in high arousal, but they aren’t the specific effect caused by redirecting blood to muscles.
