Relaunch of the Scholastic Science Readers with brand new covers, photographs, and interior designs.A very simple introduction to the major parts of the human body and how they work together to keep us alive. The importance of the brain is clearly discussed, and how our various senses send messages to the brain. Acting on these messages takes energy, which comes from food. The body also needs oxygen. Blood enables us to use both oxygen and the energy from our food. Awake or asleep, our bodies are amazing!
