Transfusion Reactions Resulting from Mismatched Blood Types If donor blood of one blood type is transfused into a recipient who has another blood type, a
transfusion reaction is likely to occur in which the red blood cells of the donor blood are agglutinated.
It is rare that the transfused blood causes agglutination of the recipient’s cells, for the following
reason:
Overview of the Circulation; Biophysics of Pressure, Flow, and Resistance The function of the circulation is to service the needs of the body tissues—to transport nutrients to
the body tissues, to transport waste products away, to transport ormones from one part of the body to
another, and, in general, to maintain an appropriate environment in all the tissue fluids of the body for
optimal survival and function of the cells. The rate of blood flow through many tissues is ontrolled
mainly in response to tissue need for nutrients.
