HEAD 
Your head contains lots of important bits: 
EYES to see / NOSE to smell and breathe / MOUTH to eat and speak / EARS to hear /
BRAIN to think
BRAIN
Brain is inside your head.
It can thinks, feels and decides. 
It can send messages to make all the bits inside your body work.
Your brain is soft, squidgy and wobbly like jelly. 
LUNGS 
LUNGS are like balloons, blowing up and down. 
This helps you breathe in air. 
Oxygen from the air joins blood.
HEART  [how oxygen gets to your whole body?]
Once oxygen is inside your blood, the HEART pumps the blood around the body. 
Put your hand on your chest to feel your heart beat.
# The heart is a muscle with two halves. 
One half pumps blood back to the lungs to get more air. 
The other half pumps the blood around the body.
# Tiny tubes called ARTERIES and VEINS help the blood travel right to the tips of your toes and back.
Blood is red like tomato sauce! When you cut yourself you can see it. OUCH!
TUMMY
TUMMY mixes up all the food to get energy.
When we eat food, the food travels down a tube into the tummy.
When you're hungry you can hear your tummy rumble!
[What is digestion?] Your tummy churns, and mashes your food.
SKIN
Your skin goes over your body and holds it all together. It keeps your insides in and makes sure they are safe. 
BONES
Bones are super strong and hard, like your brain and heart, don't get hurt. 
If you bump your head, your brain will be safe because it has a hard shell around it, made of bone, called your skull.
Skull / Jaw / elbow / shoulder blade / spine / rib cage / hip bone / wrist / knee cap
MUSCLE
Muscle is between your skin and bones. They pull your bones to make you move.
Your biggest muscle is in your bottom!
Did you know?
Up to 2/3 of your body is water!
[How big your heart is?] Your heart grows. However big you are, it will always be a bit bigger than your fist.
When you are sleeping, your bones and muscles stretch and grow.
