 * 2.1 The Characteristic of Systems**

Your body has many different systems that help the body work properly and to be sure that you stay healthy. For example if your respiratory system didn't work then it couldn't control your breathing and the exchanges of gases and tissue in your lungs, then your body wouldn't be the same, you'd probably be dead. All the systems in your body must have these characteristics:
 * 1) A system is made of individual parts that work together as one,
 * 2) a system is sometimes connected to one or more systems,
 * 3) if one part of system is missing or damaged, then the system may not work well or at all.
