Have you ever wondered how you can eat the things that you eat or how you can breathe or move your arms? If you think about it, it's pretty amazing that the human body can do all of the things that it does. Your body is made up of what are called systems. These systems are collections of organs and body parts that work together for a common goal. For example, your bones are all a part of the skeletal system. They work together to give your body shape and so that you can move. They also work together to protect your important organs, like your heart. The other systems that you have in your body are the circulatory, respiratory, muscular, digestive, and nervous systems. Each of these systems are very important, and everyone has them. It's important for kids to understand what the systems of the body are so that they can understand how important it is to keep the body healthy.
