  The human body is a complex arrangement of separate parts. Each part performs its own specific task, yet each is dependent on the other to maintain one unique living being: YOU. Learning about the human body and how it works also helps us examine ourselves and the world around us. When we examine the human body, we find that there are differences that make each person unique and special. However, the basic truth is that we are more alike than we are different. Body systems help the body remain alive. The skin protects the body; the body obtains oxygen through the respiratory system; the digestive system processes food so it can be used for energy and growth; the heart and blood vessels circulate oxygen and other substances through the body; the kidneys eliminate waste materials; and the reproductive system produces offspring. Together the nervous system and endocrine system form a command system that links all of the other body systems. Come and take a look some of the body systems. It will be an enjoyable adventure.
