What is more important Heart or Brian?

Both are very important.DETAILS-THE HEART: Some would say the heart is more important because it pumps blood to all parts of the body, including the brain. Without the blood in the brain, the brain would not be able to control involuntary activities such as heart beat. Basically, the brain needs the heart to pump blood to it.THE BRAIN:There is one part of the brain that controls involuntary activities such as heart beat. (The name of that part is the medulla) Without the medulla, the heart would never be able to pump blood to other parts of the body. Even though, you still need the heart to pump blood to the brain to let it function and control.OPINION-In my opinion truly, I think the heart is the most important because of the latest technology, machines are able to act like medullas and control heart beating. But, in order to live a wonderful life, both organs the heart & the brain are needed. :) DEFINITIONS-Involuntary activities- actions that the body cannot control, it just happens. (examples: breathing, digesting, heart beat.)Medulla- a part of the brain that connects the spinal cord to the brain.
