Fast Facts About Blood - Overview
BLOOD:
Everyone Has It... Everyone Needs It
This red liquid carries oxygen and nutrients to every part of the body and carries carbon dioxide and other waste products back to the lungs, kidneys, and liver for disposal. Blood fights against infection and helps heal wounds so we can stay healthy.
There's no substitute for blood. If people lose blood from surgery, an injury, or if their bodies can't produce enough, there is only one place to turn -- volunteer blood donors.
