Blood Is Made Up Of 5 Major Components:
-
Under Construction
Platelets are the construction workers in your blood. They throw themselves into wounds, grab onto each other using
fibrin, and make a seal to stop bleeding and keep germs out.
-
Seek & Destroy
White blood cells can leave the blood vessels which transport them. They move freely among the body's cells seeking
out and destroying germs.
-
Special Delivery
Red blood cells are constantly loading and unloading. It takes less than a second for a red blood cell to unload
its cargo of oxygen and pick up a load of carbon dioxide waste in its place.
-
Working Mothers
Stem cells in your bones "give birth" to new red blood cells. In the second it takes to blink your eyes, over a
million new cells are born and old cells are replaced.
-
Taxi!
Plasma is the liquid part of your blood. It transports and delivers blood cells, nutrients, and important messengers
called hormones throughout the body.
