What part of the brain tells the heart to pump?

It connects the higher parts of the brain to the spinal cord (see the picture at the right of this page). The cardiac, respiratory, and vasomotor control centers are in the medulla.

The heart does not need a brain, or a body for that matter, to keep beating. The heart has its own electrical system that causes it to beat and pump blood. Because of this, the heart can continue to beat for a short time after brain death, or after being removed from the body.
