How does our circulatory system keeps us alive? | BBC Teach

This clip explains how the heart and circulatory system work, taking a close look at the four chambers, two sides and the valves of the heart.

                                     How does the heart work?      

                                 

Label the heart:

                                

What's in your blood?

(Watch the video then do the quiz)

                               

Let's get science-y

Have a go at making blood! Yes...you read it right...blood!

It will help you to understand exactly what our blood is made up of.

 

 

   What you need:

  -    Yellow and red food dye

  -    2 large handfuls of Cheerios 

  -    Some mini white marshmallows

  -    Little bits of purple paper 

  -    A large clear bowl or a clear bottle

  -    A zip lock bag or a sealed bag

 

If you haven't got any of these things, you could improvise. For example instead of mini white marshmallows, you could use little bits of white paper. Yellow food dye isn't essential so you could do without that.
