About Blood

Blood Saves Lives

Blood carries oxygen and nutrients to all parts of the body, and carries carbon dioxide and other waste products back to the lungs, kidneys and liver for disposal. It fights against infection and helps heal wounds, so we can stay healthy. There's no substitute for blood. If people lose blood from surgery or injury or if their bodies can't produce enough, there is only one place to turn - volunteer blood donors.
