Everyone Has It
Everyone Needs It
This red liquid 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.
Blood has a 42 day shelf life. Because of this fact it is important for RRVBC to keep a continual blood supply on hand.
What is Blood?
Blood Cells Are Produced in Bone Marrow
Red cells, white cells and platelets are made in the marrow of bones, especially the vertebrae, ribs, hips, skull and sternum. These essential blood cells fight infection, carry oxygen and help control bleeding.
Plasma Carries Blood Cells
Plasma is a pale yellow mixture of water, proteins and salts. One of the functions of plasma is to act as a carrier for blood cells, nutrients, enzymes and hormones.
White Cells Defend The Body
White cells are the body's primary defense against infection. They can move out of the blood stream and reach tissues being invaded.
Platelets Help Control Bleeding
Platelets are small cell fragments in the blood that control bleeding. They form clusters to plug small holes in blood vessels and assist in the clotting process.
Blood Safety and Testing
Blood centers follow five layers of safety procedures: blood donor eligibility standards, individual screening, laboratory testing, confidential exclusion of donations, and donor record checks.
