Question

Quizplus · Accepted Answer

The body's initial physical response to stress is the activation of the sympathetic nervous system, which causes the release of adrenaline and the dilation of the vascular bed. This results in large amounts of blood being pumped to the muscles of the arms and legs to prepare for fight or flight response. However, this can also result in a decrease in blood flow to the brain, which could lead to syncope (fainting). Therefore, choice B is the correct answer as it describes the dilation of the vascular bed.
