BCNI visit The Jes primary school in Galway

Blood in our bodies is pumped by the heart through a network of arteries and veins. Blood also carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system; from there they are removed from the body. Without blood, we couldn't keep warm or cool off, we couldn't fight infections, and we couldn't get rid of our own waste products.

So how exactly does blood do these things? How is it made, and what's in it? How does blood clot? 

BCNI staff went along to The Jes school to tell the 6th class kids a little about the mysterious, life-sustaining fluid called blood.
