Human Body

With 11 organ systems, 206 bones, over 30 trillion cells, and a multitude of unplanned circumstances, the human body has many moving parts working at once! Each organ, bone, and cell has a specific job to perform, but every job affects another job to make sure the body can carry out everyday functions. In this volume, readers learn about some key cause-and-effect processes that are going on in their body, as well as how choices they make can affect their body functions. As engaging illustrations correspond with helpful arrow diagrams, readers develop a deeper understanding of how cause and effect works, as well as how it works within their own bodies.
