The Human Body & Environment: How Our Surroundings Affect Our Health, The Muscular & Skeletal Systems (Middle School Reference) - Tapa blanda

If someone dropped you on the moon without an astronaut's equipment, what would happen? You'd die, of course. The human body depends on its environment. This engaging four-volume set, written at the sixth- through eighth-grade reading level, examines our bodies' inseparable relationship with the environment. Each volume presents the parts of a particular body system and how they work, things that go wrong and how they're treated, how the environment affects the particular body system and impacts our health, controversial environmental issues (where applicable), and changes individuals and groups are making to fix environmental problems and restore health. The skeletal system is the body's frame, upon which the muscles, organs, and skin hang; muscles help us to walk, bend, blink, and breathe. Various kinds of pollution, including harmful radiation, can cause improper growth in muscles and bones or impair their functionality. This volume covers how these dynamic systems work properly, how the environment impacts their operation, and how doctors and therapists work to maintain and treat them.
