Question
Transcribed Image Text:Directions: Choose the one best answer to each item.
Items 1 to 5 refer to the following
information.
In the 1800s blood transfusions were
practiced; blood was transferred from one
person to another. Sometimes the
transfusions were miraculously successful,
while at other times persons experienced
pain, tingling sensations, and often death. In
1901 a scientific basis was recognized for
successful transfusion of blood. It was
realized that blood had to be divided into
groups, and only certain types could be
transfused successfully to a given individual.
If an incompatible blood type is transfused
into a person, the blood cells will clump
together in a reaction called agglutination.
Agglutination is due to a reaction between
antigens and antibodies in the blood. An
antigen refers to any substance that produces
an immune response; usually the body reacts
by producing antibodies. The antibodies fight
off the antigens, which are considered
invading substances.
The best-known system of antigens in the
blood is the ABO system. The surfaces of red
blood cells of blood types A, B, and AB
contain certain substances that act like
antigens. The safest transfusion of blood
takes place when the donor and recipient
have the same type of blood. Otherwise, two
of the most critical factors are the antigens
contained in the donor's blood and the
antibodies contained in the recipient's blood
plasma. Antigens and antibodies should not
oppose one another. If the red blood cells
containing these antigens are transferred into
a person whose blood plasma contains
antibodies against them, clumping occurs.
