Focusing on contemporary and historical developments in the study of human anatomy, Eyewitness: Human Body features clear, age appropriate text, photographs, charts, graphics, and 3-D models highlighting the inner workings of our bodies — from the framework of our skeleton to the millions of tiny cells that make our bodies work. In this updated edition, kids can discover how muscles and joints help us move, find out how x-rays work, see the network of nerves inside the human head and more in a format that makes complex scientific concepts easy to understand. The introduction of paperback editions, eye-catching jackets, and updated interiors ensure that the Eyewitness series will continue to be relevant in the ever-changing world of education and remain the go-to source for homework help, research projects, reluctant readers, ESL students, and, as always, to satisfy the minds of curious kids.
