There are different types of blood cells with different jobs.
Narrator: Blood gets around our bodies through a system of blood vessels.
To picture the blood vessels, imagine a busy network of roads.
And those roads are always full of little vans which are busy making deliveries and rubbish trucks picking up rubbish and police cars looking out for intruders.
Police: We have a suspect heading full speed towards the stomach. Require immediate backup!
Narrator: Your blood has different cells with different jobs.
Some cells do repairs if you get a cut.
Red blood cells deliver oxygen and take away rubbish.
And your white blood cells are like police looking for germs.
There's a lot going on inside you!
Blood transports materials around the body and protects against disease. It contains:
- Red blood cells which transport oxygen.
- White blood cells which protect against disease.
- Blood platelets which help the blood to clot and repair a cut.
- Plasma which is a liquid that carries these cells. It also transports important nutrients.
