Format: PDF / Kindle (mobi) / ePub
Everything you need to know about the human body – in a quirky package, in ebook format. Open up the shiny cover and show your child how all the bony, bloody and squelchy goings on inside their bodies make it work. They'll get the lowdown on everything from human cells and senses to brain structure and body systems. Take a trip through the history of medicine and body science from Hippocrates to the Human Genome Project. Find out more about left-handedness, memory tricks and what sensory skills are needed to be a professional food taster! Quirky twists and concepts tick the side-splitting box - where else are they going to find the digestive system modelled out of balloons, dinosaurs checking out a human skeleton in a museum, or a cartoon strip telling the story of the discovery of penicillin? A gutsy, cheeky, sick, hip, nosey, heady, handy, mouth-watering and eye-catching look at the human body!

Wax models (ﬁgure 6) There were not always enough cadavers to go around, so intricate wax models were made to help anatomy students learn. They showed body structures in complex and realistic detail. During the Renaissance, Italian anatomists cut up cadavers to identify major organs, and depictions of the human
