Final answer:
The sympathetic nervous system prepares the body for fight or flight responses in dangerous situations.
Step-by-step explanation:
The sympathetic nervous system is responsible for the "fight or flight" response that occurs when an animal encounters a dangerous situation. Examples of functions controlled by the sympathetic nervous system include an accelerated heart rate and inhibited digestion. These functions help prepare an organism's body for the physical strain required to escape a potentially dangerous situation or to fend off a predator.
