El sistema óseo (The Skeletal System)
From the Series Libros sobre el cuerpo humano para madrugadores (Early Bird Body Systems)
The skeletal system is made up of bones. They support and protect your body and help it work. Some bones help you run, or pick up a pencil; others protect organs, like the skull, which protects your brain. Learn about bones, joints and more in this informative book.
