What makes the brain tell the heart to pump blood around the body?

The brain doesn't control the heart. The heart controls itself. If you would take a single heart muscle cell, it will beat on its' own. Add another and they beat together. The heart has special muscle cells called pacemakers. The primary one is called the SA (sinoventricular) node. That sets that pace or rhythm. There is also a slower back up pacemaker called the AV (atrial ventricular) node.

What part of the brain controls your heart beat?
The adrenal medulla is the part of the brain responsible for the release of adrenaline, when the adrenaline is released into the blood, the SAN is stimulated to work faster and increase your heart rate, this happens when playing sport or during your fight or flight response. However, the heart is not controlled by your brain as it is a myogenic muscle (self-exciting) this means that if you were to remove the heart from a body it would continue to beat. The sino-atrial node is responsible for the excitation of the heart. :) Hope this helps. Steph :)
