1. Skeletal System By: Kate, Keeley, Charlie and Dr. Bennett

2. Organs that make up the skeletal system ~Bones ~Bone Marrow ~Tendons ~Ligaments ~Cartilidge

3. Explanation on how the system works ~It supports the body ~It protects vital organs ~Works with muscles so you to move

4. Diagram on how the system works

5. Disorders Associated with the system ~Osteoporosis: weakens bones ~Osteoarthritis: joint cartilage becomes damaged by wear ~ Scoliosis: curve in the spine ~Spina Bifida: a birth defect in which a portion of the spine does not fully develop

6. Continued… ~Paget’s Disease: an abnormal breakdown of bone tissue due to abnormal bone growth ~Fracture: -Simple fracture: a bone breaking but the skin remains intact -Comminuted fracture: a bone splintering -Compound fracture: a bone breaks and penetrates the skin ~Bone cancer ~Kyphosis: a rounding of the upper spine

7. How the skeletal system works with another system The skeletal system can work with the muscle system. What it does is the muscles connect to your bones and they contract and help your skeleton move.

8. How to keep your skeletal system healthy One way to keep this system healthy is to get a good supplement of calcium to keep your muscles strong. Another way is to have a good amount of amble nutrients. Lastly is to keep a good posture to reduce vertebra and bone injuries.

9. How do drugs alcohol or tobacco affect this system Alcohol reduces the ability to absorb calcium to keep the bones strong. Tobacco can affect the system by making the bones brittle.
