If the brain controls and functions many of the human bodie's organs, what makes the human brain function?

The simple answer is that the brain controls itself - after all it is the seat of consciousness and has a far more complicated feedback mechanism compared to the other organs. Your 2 part question are really quite separate things - you have to look at the brain on its own and I recommend you shop for a book on basic neurobiology though some popular science books on the brain are more informative in many ways.If the brain controls and functions many of the human bodie's organs, what makes the human brain function?
Human brain is controlled by external sources reflected by human senses (sight, hearing, touch, smell, taste) as well as by internal sources (heart, lungs, stomach, blood etc.).


So we can consider a brain as the most sensitive organ of a human body.If the brain controls and functions many of the human bodie's organs, what makes the human brain function?
The Inteligent heart is what runs the machine. Brain and heart working together keeps you up and running and keeps all of the other parts healthy.
Proteins.
The brain is made up of nerve impulses and the fuel you put in your body controls the chemical acetycholine, which is produced in the nervous system. These impulses look like electrical activity when recorded. The brain is fed through many blood vessels.


This is short and sweet but this is the very most basic way of putting it. You can learn more by taking classes in anatomy and physiology which really teaches you how the human body functions.
the thing that controls human brain is its organs.


heart provides brains required blood containing oxygen so heart controls the brain
