Do YOU know your heart? (2)

Your blood is made up of billions of  cells floating in a liquid called plasma.  It’s like a river that flows to every part of your body through your arteries, veins and capillaries.

The red cells in your blood stream are like freight ships that carry oxygen from your lungs to your tissues and take waste gas (carbon dioxide) from your tissues back to your lungs.

The white cells in your blood stream are like Coast Guard boats that are always on alert and act like dams to shut off the flow of blood whenever you cut yourself.  They form tiny threads called fibrin which trap the red cells forming a clot or dam.

A crop of blood only 1/25th of an inch in size contains about 5,000,000 red blood cells, 7,000 white blood cells and thousands of platelets.  60,000 of these blood cells could be put on the head of a pin!

Amazing isn’t it?
