Blood Donation Facts:Blood Donation Facts:Each blood donation saves

approximately three lives, and usually takes less than one hour of your time.

Healthy donors are the only source of blood. There is currently no substitute.

Nearly 5 million people need transfusions each year.

1out of every 7 people entering a hospital need blood.

Components of BloodComponents of Blood Red Blood Cells: Blood cells that carry oxygen throughout

the body and give blood its red color. They are transfused to people who fail to produce their own, have severe bleeding, or a low blood count.

Platelets: Cellular fragments. Their primary function is to prevent bleeding. They play a part in the body's clotting mechanism. Used to help transplant and cancer patients.

Plasma:Plasma The liquid portion of the blood. It contains coagulation factors and is used to treat patients who develop bleeding problems during major surgery or massive trauma. Because some of the factors lose effectiveness quickly, plasma must be frozen in order to preserve its functions. Used to help liver transplant patients and those who have open heart surgery.
