The key (for the host: fold this page back)
- C: cones. Each eye has about 120 million rods, which see in black, white and gray.
- B: ruminants. Their complex stomach turns tough plants into energy and building blocks for the body.
- B: tendons. When a muscle pulls, its tendon and the bone move along with it.
- B: algae. The grooves run from the top to the bottom of each brownish-gray hair.
- A: floating ribs. They can't float away: like all ribs, they are fixed to the spine in back.
- A: the cochlea. Tiny hair cells inside it help turn sound into electrical signals for the brain.
- C: hemoglobin. Blood turns bright red when hemoglobin picks up oxygen in the lungs.
- B: alveoli. Each person has hundreds of millions of alveoli in their lungs.
- A: the cerebellum. It is much smaller than the cerebrum but lets you stand up and move around.
- C: the epidermis. Below it is the dermis, which holds nerve endings, blood vessels and sweat glands.
