  3. Skeletal System The skeletal system is made up of bones, ligaments and tendons. It shapes the body and protects organs. The skeletal system works with the muscular system to help the body move. Marrow, which is soft, fatty tissue that produces red blood cells, many white blood cells, and other immune system cells, is found inside bones. The smallest bones in the body are found in the ear. The longest bone in the body is the femur. The bones are filled with a fatty substance called bone marrow. In this marrow, red and white blood cells are manufactured and then released into the bloodstream. Over half the body's bones are in the hands and feet. The only joint less bone in your body is the hyoid bone in your throat. As your bones grow, you get taller (of course). Your growth in height is likely to stop by the time you are 16 if you're a girl and 18 if you're a boy.

  4. When you were born, your skeleton had around 350 bones. By the time you become an adult, you will only have 206 bones. This is because, as you grow, some of the bones join together to form one bone. The skeletal system provides five important primary functions: support, protection, movement, storage and blood cell formation. Calcium storage is a function of the skeletal system.

  6. How do we keep our skeletal system healthy Drink plenty of calcium in the form of milk. Or, if you don't care for milk, take vitamin supplements, especially those that contain calcium and vitamin D. You can also obtain calcium from cheese, yogurt and other calcium-rich foods. Calcium also protects the bones from age-related conditions such as osteoporosis. Maintain a diet rich in calcium such as orange juice, broccoli, fish and pastas and rice. Maintain normal weight ranges to help keep excess weight off bone joints. Ingest adequate amounts of calcium on a daily basis throughout life for optimal bone strength and health.

  7. Engage in weight-bearing exercise. Exercise is vital for the strength of bones and can involve anything from swimming to walking to dancing. However, weight-bearing exercise is also important to help strengthen not only muscles but bone structure and density as well. Walking is considered a weight-bearing exercise, so you don't have to go to the gym to pump iron to perform weight bearing exercises. Keep teeth clean and healthy. A cavity in a tooth may serve as a major point of entry for bacteria or may grow infected, allowing bacteria to spread into the body, slowly destroying the roots of teeth, the jawbone and even making its way into the sinus cavities Wear protection when engaging in contact sports like football, rugby and hockey, just to name a few. Wearing a helmet when riding bikes or motorcycles may protect the skull and neck from serious injury in the event of an accident.

  8. How does the skeletal system work? The skeleton is a frame. The muscles are attached to the frame by tendons. We flex out muscles and it moves our frame. Each part of the body that moves is controlled by the muscle above it. For example: when you flex your fingers it is controlled by the muscles in your hands, your hands are controlled by the muscles in your forearms, your forearms are controlled by the muscles in your upper arms. The skeletal system works by dependence on the muscular system for movement. Without it the body will not be supported. It also serves as a shield to vital organs.
