Body Systems: Cardiovascular System: Components of Blood
Makes up 55% of your blood. It's a thick liquid that carries that transports food and waste.
These cells are significantly larger than red blood cells, and there are far, far fewer of them in your blood. These cells clean-up old blood cells and fight the germs that enter your body.
Shake some non-pareils into your blood model.
You now have a cup of "blood". You'll notice that much of it is liquid, but there's lots of solid in it as well. You'll also notice lots of red blood cells with the occasional white blood cell popping up. You have to look really hard to see the platelets - both because of their small size and because of their small numbers.
