Typically, we tend to focus on our blood when we get a paper cut, donate, or find ourselves at the hospital. The truth is there’s a lot more to the life-sustaining fluid that drips into a testing tube, a band-aid, or an intravenous (IV) line. Without blood, our bodies would be unable to receive the adequate supply of fuel and oxygen to reach the billions of cells all essential for good health. Every two seconds someone in the U.S. needs blood. More than 41,000 blood donations are needed every day, and a total of 30 million blood components are transfused each year in the U.S., according to the American Red Cross. Blood is necessary for our existence, since it carries oxygen and essential chemicals needed in the body while also picking up and delivering waste that different parts of the body no longer need. Therefore, it’s important to learn some little-known facts about the life-sustaining fluid that helps our bodies function.
