The document discusses the skeletal system and its structures and functions. It describes how bones are stacked to help one stand up and how the skull protects the brain. It notes that the skeletal system has 12 pairs of rib bones that protect internal organs. It also discusses how the muscular system relies on bones and how maintaining bone health requires a nutritious diet, calcium, and exercise.

3. The structure is: Blocks that are stacked on top of each other. The function is: To help you stand up.

4. The structure is: A complex collection of different-sized and shaped bones designed around a specific purpose. The function is: Cranium that protects the brain.

5. Structure is: 12 pairs of bones. Function is: To protect internal organs.

6. Structure is: A perfectly cylindrical bone. Function is: To walk, jump, kick, swim and other actives that involve your leg.

7. The muscular system relates to the skeletal system because the muscular system uses the bones for their action. Without bones muscles would be useless at distance. Bones act like lever arms to increase the force produced by muscles.

8. Maintain a nutritious diet. Appropriate amounts of calcium. Exercising regularly.

11. The largest bone is the pelvis, or hip bone. In fact it is made of six bones joined firmly together. The longest bone is the 'femur', in the thigh. It makes up almost one quarter of the body's total height. The smallest bone is the 'stirrup', deep in the ear. It is hardly larger than a grain of rice.

12. The ears and end of the nose do not have bones inside them. Their inner supports are cartilage or 'gristle', which is lighter and more flexible than bone. This is why the nose and ears can be bent. After death, cartilage rots faster than bone. This is why the skulls of skeletons have no nose or ears. The longest bone is the 'femur', in the thigh. It makes up almost one quarter of the body's total height. The smallest bone is the 'stirrup', deep in the ear. It is hardly larger than a grain of rice.
