1. Why is it important to type blood before giving someone a transfusion?
2. What are antigens and antibodies? How are they involved in the human body’s
response to incompatible blood?
3. Describe the immune response when a person receives a transfusion of
incompatible blood. Why is this dangerous?
4. Blood Type O is a universal donor. Using your knowledge of blood typing and the
immune system, explain why this is true.
5. Using your knowledge of the immune response and blood typing, explain why
people with type AB blood are universal recipients.
6. Which, if any, of the blood samples tested can the patient with Type B+ blood
receive? Explain why.
7. Explain how you were able to use your knowledge of how different types of blood
react with Anti-A, Anti-B, and Anti-Rh antibodies to determine the blood types of
the three samples.
8. If a person has Type A blood, he or she would have antibodies for what blood
type?
9. If a person has Type O blood, what type(s) of blood could they not receive?
10. Is knowing the ABO blood type of a potential blood donor enough to determine a
suitable match? Explain your answer.
