Discover the human body in glorious technicolour!With eye-grabbing diagrams and amazing facts, The Heart, Blood and Lungs takes a vibrant look at some of the body's most important systems. There are trillions of cells in our bodies, each one needing oxygen to survive. This book explores how the heart, lungs and blood work together to supply oxygen to the rest of the body. Mind-bloggling facts (for instance, your blood vessels are long enough to stretch around the world two and half times!), and clear and straighforward diagrams help to explain the important functions of your heart, lungs and blood, while unique photos enable the reader to see the human body in a whole new light. This colourful and fact-packed series provides an accessible look at the human body through bright and bold graphics. With spread-filling diagrams, a colour-blocking approach, and simple text and captions, The Bright and Bold Human Body presents the incredible scale and complexity of the human body in small, digestible chunks. As well as this, surprising statistics and close-up photos allow children ages 7+ to gain an insight into the wonders of our bright and bold bodies.
