Amazon.com description: Product Description: A human kidney, a brain, a heart, an eyeball, and a plastic skeleton with removable parts are assembled in this unusual and instructive kit for budding junior biologists. The shapes of all organs are accurately rendered, and an accompanying book is filled with full-color illustrations and descriptions of the human body's organs and functions, described on a level that is understandable to older children. The book describes the human body in a series of 14 two-page spreads. The body parts and functions described include the senses, brain, lungs, heart, blood, muscles, bones, stomach, intestines, liver, kidneys, and cells. Illustrated overlays show the human body's skeletal and muscle systems. The book and models of organs are attractively packaged in a book-shaped box. The book slips into a pocket on the box's inside cover, and a see-through window shows all model body parts when the imitation book cover is lifted.
