Muscular System

By...Ella, Emily and Jamie

Definition Muscles are flexible organs consisting of a special bundle

of tissue which moves particular bones or parts of the body.

Your bones form your body’s framework, but they cannot move by themselves.

About 620 muscles allow you to make body movements.

Lots of your muscles allow your internal organs such as the heart and stomach to work.

Problems

Muscles cramp if they do not get enough oxygen. If you get cramps your muscles go into spasm.

Sometimes when they don’t work it’s dangerous.

Problems with your muscles can cause serious injury or death.

We really need to keep in shape so we can be healthy and safe.

Taking Care1) Exercise

2) Eat nutritious meals

3) Having good self esteem and avoiding stress allows your muscles to relax.

4) Exercise clears your body of toxins.

5) Walking, jogging, swimming, cycling and climbing all help.
