No, a human couldn't live without a brain because the brain controls everything in your body, so it tells your heart to beat, feet to move, eyes to blink, mouth to open, teeth to chew. If you don't have your brain to tell your heart to beat, your heart cannot pump blood. So your body really can't live.
The body of a person who is brain dead can be kept alive indefinitely, but if the person is truly brain dead, then the person will never revive. Such a body can live even withâ¦out a respirator, because the brain stem is still functioning and controlling the basic body functions like breathing and heart beat. The brain stem is the most primitive and basic part of the brain. Physicians are the best people to help decide if a person is brain dead.
