I've divided into three parts
This little story rhyme.
I hope that you'll enjoy it
And be glad you spent the time.

Part 1

There's a tiny world inside my bones.
I learned of it one day,
When some bullies came to visit
And decided  they would stay.

Before they came, this little world,
Was happy as could be,
With platelet cells and red blood cells 
And white ones having tea.

These little cells inside my bones
Grew up and worked each day.
They traveled in my blood stream,
Making sure I felt OK.

The white blood cells were body-guards,
Protecting me from germs.
They used to know some special tricks
That made invaders squirm.

The red blood cells were round and strong,
And carried on their backs,
The oxygen my body needs
To play and to learn facts.

The platelet cells were sticky friends,
In charge of making clots.
I’d cut my hand or scrape my arm,
They’d make the bleeding stop.

Well that’s the way it used to be
Before the bullies came.
I hadn’t met this inside world.
I knew nobody’s name.
