1. The Skeletal System
Time to “Bone-Up”
on a Few Things!

Your skeletal system protects your organs.
It keeps you standing up.
Your bones are a blood factory.
Your blood cells are made in your bone marrow.
Your bones help you move.

of our body.
blood cells are made
inside our bones
bones help us move

ball and socket (like your shoulder)
hinge (like your wrist)
gliding (like your vertebrae) and
pivot (like your neck).

Joints are where
your bones meet.

10. How Are Bones
Held Together?

11. Cartilage Cartilage is bendable- not hard like bones.
It can be found in many parts of your body.
It is found in-between bones so they don’t rub together.

They also fasten bones together
They are as
strong as a rope
