Human Body Systems (Overview)

Your body is made of many parts that team up to keep you alive. We group those parts into body systems. Each system has a special job, and the systems work together every second of the day — even while you are sleeping. When you understand what each system does, you can take better care of your body and notice when something is wrong.
