The Abo Blood Group
- Type A blood individuals have antibody anti-B in
their blood plasma. Type B blood individuals have
antibody anti-A. Type AB blood individuals have no
antibodies. Type O blood individuals have both
antibodies anti-A and anti-B.^
- Type AB individuals are known as universal
recipients because they can receive any blood type in
a transfusion.^
- Type O individuals are known as universal donors
because they have no antigens and their blood can be
transfused into any blood group.
The Rh Blood Group
- This blood group was named after the Rhesus
monkey in which one of the eight Rh antigens was
discovered.^
- The most important Rh antigen is antigen D. People
with this antigen are Rh positive; those without it are
Rh negative.^
3.^ Most Americans are Rh positive.^
4. Anti-Rh antibodies develop only after exposure to
Rh-positive blood in an Rh-negative individual.
Therefore, second transfusions can cause
agglutination.^
- Rh-negative mothers carrying an Rh-positive baby
can be treated with a drug called RhoGAM to protect
the developing fetus.
Review Questions
- Classify blood cells into three major categories with
subdivisions when appropriate.^
2.^ List the functions of blood.^
*3. How does the anatomy of the red blood cell allow it to
carry oxygen and carbon dioxide gas?
Chapter 13- Name the four categories of ABO blood groups.^
5. Why must blood groups be matched during a blood
transfusion?^
6. Explain the clotting mechanism.
