Final answer:
The sympathetic division of the autonomic nervous system speeds up the body during the "fight or flight" response by increasing heart rate, dilating bronchi in the lungs, dilating pupils, activating sweat glands, and increasing blood pressure.
Step-by-step explanation:
The sympathetic division of the autonomic nervous system is responsible for speeding up the body during the "fight or flight" response. This response is triggered when the body perceives a threat or danger. During the "fight or flight" response, the sympathetic nervous system increases heart rate, dilates the bronchi in the lungs for increased air exchange, dilates the pupils, activates sweat glands, and increases blood pressure to prepare the body for action.
