  1. Blood has many important functions. It serves as the body's delivery system. It supplies the cells with oxygen from the lungs and carries waste, in the form of carbon dioxide, back to the lungs to be expelled. It carries hormones, nutrients and waste to be used in or eliminated from different systems in the body. White blood cells help with immune system defense against illness or infection. And when you get a cut or scrape, your blood clots to keep you from bleeding fatally.
