Answer:
The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.
Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
Explanation:
If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.
