Why our heart is not the main part of the body but the brain?
In the context of complexity, the brain is a very complex organ in comparison to the heart which is a simple organ. It has one very simple job to do and that is to pump blood.
But, in the context of their dependency and relationship.
If we talk about the heart, it does not need a brain, or a body for that matter, to keep beating. It has its own electrical system that causes it to beat and pump blood throughout the body via the circulatory system and because of this, it can continue to beat for a short time even after brain death, or after being removed from the body.
Our heart can make an independent decision bypassing the cerebral cortex of the brain with a surprising electromagnetic field 5,000 times powerful than what the brain produces and 60 times greater electrical field more than the activities in the brain.
If the heart stops working the brain or the whole body doesn’t get oxygenated blood and stops working. Our brain can survive for up to about six minutes after stopping the heart.
So, from the above explanation, we can understand that the Heart is an important organ than the brain. A brain needs a heart for oxygenated blood to function but a heart doesn’t need a brain for beating.
