About the Blood
With the advancements in science we now know quite a bit about this liquid that courses through our bodies. We know there are various blood types, we know what it's composed of and it's essential functions.
Blood is composed of plasma, red blood cells, white blood cells, and platelets.
Did you know that plasma makes up half of your blood? It is the liquid part that keeps it moving. How many of you thought it was just something you could donate in college to help make extra money? The red blood cells carry oxygen and white blood cells provide an internal defense. Lastly, the platelets cause the clotting factor in blood. When you have an insufficient amount of platelets is why people with illnesses, like leukemia, often need transfusions
Did you know that prior to the 20th century transfusions were often deadly? It wasn't until 1900 that an immunologist named Karl Landsteiner discovered that there were different blood types. This discovery explained why some transfusions were fatal. If blood types are mixed the immune system attacks and breaks down the new foreign blood cells. If you are a blood type O you are considered a universal donor. This means your blood type can be given to anyone. In the book "Eating Right for your Blood Type" it is believed that the O blood type was the original blood type and the others developed as we became a more agricultural society. Maybe this is why it is accepted by all other blood types.
Consider donating - each blood donation has the potential to save up to three lives....who knew?
