Blood is like a delivery truck!
Think of every cell in your body as a little house. The blood is a big delivery truck that brings good things and takes away trash.
- Brings air: Blood picks up oxygen (the air your lungs get) and carries it to the cells.
- Brings food: Blood carries small bits of food from your tummy to the cells so they have energy.
- Takes away trash: When cells make energy, they make waste like carbon dioxide. Blood picks that up and takes it to the lungs and kidneys so the body can get rid of it.
There are little helpers in the blood:
- Red blood cells = the delivery trucks that carry oxygen.
- Plasma = the watery part that helps move things around.
- White blood cells = the helpers that fight germs.
- Platelets = the tiny bandages that help stop cuts from bleeding.
Easy pretend-play activity
Play is a fun way to remember:
- Give your child small soft toys or paper bits as 'oxygen' and 'food'.
- Have them walk (be the blood) and put the 'oxygen' and 'food' into small boxes that are the 'cells'.
- Put a different paper piece in the cell to be 'trash' and have the child carry it to a 'trash box' (the lungs or kidneys).
That shows how blood drops off good things and picks up the stuff cells don't need. Blood helps keep your body working and healthy!
