Get to grips with your heart and lungs! This title takes readers on a visual tour of the heart and lungs, explaining how the heart keeps us alive, its key function in the circulatory system and how our lungs help us to breathe. Further sections on blood cells, carbon dioxide and how to maintain a healthy heart and lungs provide informative links to help readers visualise how body parts function simultaneously to keep us going. Fun experiments and activities include making your own stethoscope, fake blood and measuring your pulse. Following on from the successful Science Crackers series, Body Works explores the science of the Human Body. Bitesize facts and gross stories make information easy to digest. Lively and informative text is supported by clearly labelled illustrations and detailed photographs, while questions help children to relate to science and comical cartoons help them to visualise scientific facts. - from Amzon
