What is blood made of?
Thank you for writing to ASK CLASSBRAIN! You've asked a great question and
we've included a partial clip from a website called Red Gold: The Epic Story
Blood is a mixture of cells and a watery liquid, called plasma, that the
cells float in. It also contains other things like nutrients (such as
sugar), hormones, clotting agents, and waste products to be flushed out of
There are three kinds of cells in the blood: red blood cells, white blood
cells, and platelets. Red blood cells carry oxygen from the lungs throughout
the body, white blood cells help fight infection, and platelets help in
clotting. For more detailed information, visit their website at:
