btn donating blood

This video was about how blood can save loads of lives.

1 of 3 Australians will need blood. There are about 5 litres of blood in our body and half a litre can save three lives.

To donate you must be 16 or over and in good health so you don’t spread diseases.

Blood is boxed up and put in a machine to process it. If the blood is whole blood it goes into a centrifuge to separate the layers. Why does our blood contain different materials? How does a centrifuge separate blood from the other liquids? I understand that it’s extremely important to donate blood.
