The skeletal system allows the body to move through muscles attaching to bones, protects vital organs by acting as "body guards" for things like the heart and lungs, and produces blood cells in the bone marrow. Bones need calcium and exercise to stay healthy - calcium is obtained through milk while weight-bearing and muscle-strengthening exercises keep bones and muscles strong. The document provides information about bone function and health and encourages exercising to have strong bones.

3. Think Quick
• What do you do everyday that requires
the use of your skeletal system?

4. The Function of Bones
• There are 3 major functions of the bones:
1. Allow the body to move
2. Protect vital organs
3. Produce blood cells in the marrow

5. Allows the Body to Move
• Muscles are attached to
bones.
• Muscles pull on bones so we
are able to move.
• Muscles wouldn’t be able to
move us and do their job
without the help of bones.

6. ProtectsVital Organs
• In order for your internal organs to stay healthy and functional,
they need to be protected.
• Bones are like body guards.
• For example, the ribs help to protect organs such as your heart
and lungs which are vital to survival.

7. Produces Blood Cells in Marrow
• When oxygen travels through the body, it is transported by red
blood cells which are made in the bones.
• Oxygen is needed for us to survive.

8. Think Quick
What do bones need in order to be
functional AND healthy?

9. Healthy and Strong Bones
• Bones need calcium to stay strong and functional.
• The best way for you to get more calcium in your diet is by drinking
more milk.
• Exercise keeps your muscles strong which also keeps your bones in
use.
• Continuing to stay active will limit bone deterioration.
• Participating in physical activity is linked to the growth of stringer
bones.

10. Exercises for Strong Bones
• There are 2 types of exercises for maintaining and building strong
bones
1.Weight bearing
- Dancing, hiking, jogging/running, tennis
2. Muscle-strengthening exercises
- Lifting weights, exercise bands, weight machines, standing and
lifting toes

11. Bones andYou
• It is important to
know where your
bones are and what
they do so that you
can be aware of
how to make them
stronger and
healthier for longer.
• What can you do
more of to make
your bones happy
and healthy?

12. Now get out there and exercise those bones!!
