Final answer:
During the fight-or-flight response, blood flows at a greater than normal rate to the long muscles of the extremities.
Step-by-step explanation:
During the fight-or-flight response, blood flows at a greater than normal rate to the long muscles of the extremities. This is due to the activation of the sympathetic nervous system, which causes the blood vessels in the skeletal muscles to dilate. The increased blood flow to the long muscles of the extremities is beneficial during a fight-or-flight situation as it helps to provide more oxygen and nutrients to these muscles, enabling them to perform at a higher level.
