Functions of the Skeletal system
![Page 3: 5 major functions: Provides shape and support Enables you to move Protects your organs Produces blood cells Stores minerals and other materials until](https://reader035.vdocument.in/reader035/viewer/2022062518/56649e7b5503460f94b7ca77/html5/thumbnails/3.jpg)
Shape and supportSkeleton determines the shape of your bodyVertebral column (backbone) is the center of
the skeleton

Movement and protectionYour skeleton allows you to move. Muscles pull on the bones to make the body
move.Bones protect the organs : brain, heart, lungs
Production and storage of substancesMakes blood cellsStores minerals such as calcium and
phosphorus

Joints allow bones to move in different ways.Some joints do not move – immovable joints

The bones in movable joints are held together by strong connective tissues called ligaments.
Cartilage, another connective tissue, covers the ends of the bones and keeps them from rubbing against each other.

Diet: Calcium and phosphorus – keeps the bones strongDairy products, green vegetables
Exercise: moving around makes your bones stronger and denser
