Final answer:
When the body goes into fight-or-flight mode, the oxygen in the brain is directed towards the parts of the brain that are involved in survival instincts and motor responses.
Step-by-step explanation:
When your body goes into fight-or-flight mode, the oxygen in your brain is directed towards the parts of the brain that are involved in survival instincts and motor responses. This is because the fight-or-flight response triggers the release of stress hormones such as adrenaline, which increase heart rate and blood pressure to provide more oxygen and energy to the muscles. The increased oxygen supply to the muscles and vital organs helps us respond quickly to potential threats.
