8. How do you perform these functions? Because of chemical reactions that occur in the body, you produce very small amounts of electrical energy. This electrical energy sends a message to your heart and makes it beat. There is a patch of cells in the upper right chamber of your heart called the "pacemaker" that first gets the electrical signal and then sends the signal on to the rest of the parts of the heart. There are parts in your brain that can control how FAST or SLOW your heart beats, but for normal, everyday beating, the pacemaker keeps your heart going. Some people have a bad pacemaker and need to get an artificial one. Muscles are made up of cells that work together to pull, and work like levers. When a muscle is working, it is contracting and all the cells are pulling closer and closer together.
