**5 March 2018 STEM WEEK**

We have been learning about our bodies.

“See when you’re exercising, your blood goes a wee travel round your body”

“See that red, I got blood there”

“My body fights off germs”

“The blood is coming through our bodies”

What is blood made of?

White blood cells that fight germs and infection.

Platelets that help heal cuts.

Red blood cells that carry oxygen.

Plasma helps the blood move through veins and arteries.
