Definition of Blood bank Blood bank: : A place where blood is
collected from donors, typed, separated into components, stored,
and prepared for transfusion to recipients. A blood bank may be
a separate free-standing facility or part of a larger laboratory
in a hospital. Separation of blood: Typically, each donated unit
of blood (whole blood) is separated into multiple components,
such as red blood cells, plasma and platelets. Each component is
generally transfused to a different individual, each with
different needs. An increasingly common blood bank procedure is
apheresis, or the process of removing a specific component of
the blood, such as platelets, and returning the remaining
components, such as red blood cells and plasma, to the donor.
This process allows more of one particular part of the blood to
be collected than could be separated from a unit of whole blood.
Apheresis is also performed to collect plasma (the liquid part
of the blood) and granulocytes (white blood cells). Who receives
