What is the function of the nervous system? give a real - world example of your nervous system in action.

The nervous system is responsible for coordinating all of the body's activities. It controls not only the maintenance of normal functions but also the body's ability to cope with emergency situations.

Example:
Let's say your food was hot and you touched it automatically your nervous system will tell your brain that you just touched some thing hot. That is why you realize right away.

Hope this helps
