, or white blood cells) is separated out, the remaining blood components being returned to the body. Apheresis allows the donor's blood volume to replenish itself much more quickly than whole blood donation. One type of apheresis, plasmapheresis, is commonly used in commercial blood banksblood bank,
site or mobile unit for collecting, processing, typing, and storing whole blood, blood plasma and other blood constituents. Most hospitals maintain their own blood reserves, and the American Red Cross provides a nationwide collection and distribution service.
