A&P II LAB 5: BLOOD TYPING EXAM
QUESTIONS AND ANSWERS GRADED A+
2025/2026
When and by whom was the A,B,O Blood Group Discovered? - ANS -In 1900 by Carl
Landsteiner
-This discovery allowed us to complete blood transfusions successfully.
What are the general blood types? - ANS -Type A
-Type B
-Type AB
-Type O
Prior to learning that we had a blood type... - ANS There were multiple failed blood
transfusions because of the mismatch in blood types
What is the Compatability of blood types and transfusion based on? - ANS -Red Blood Cells
-Proteins in our Plasma
What is located on our RBC's? - ANS -Antigen
Our blood type is determined by the Antigen that is present on our RBC

, What is a Antigen? - ANS It is either a protein, glycoprotein, or glycolipid. It is genetically
unique to each individual except for identical twins.
Where are Antigens found? - ANS On the surface of RBC's and they do determine the blood
type that we have. They also help to enable the body to distinguish foreign matter that may
enter the blood stream.
A Antigen on the RBC... - ANS Defines someone as having Type A blood
B Antigen on the RBC... - ANS Defines someone as having Type B Blood
AB Antigen on the RBC... - ANS Defines someone being Type AB
If someone is completely absent of Antigen on the RBC this means... - ANS They are Type O
blood type.
Where are Antibodies found? - ANS -In our Plasma
-They will detect foreign matter and start or initiate a immune response if this foreign matter is
present.
-They will bind to the antigen present on the RBC and will mark those cells for destruction.
What are Antigens called? - ANS agglutinogens
What are Antibodies called? - ANS agglutinins
How long does it take for Antibodies to appear in a individuals body? - ANS Antibodies of the
A,B,O grouping are not present at birth and appear beginning at 2-8 months after birth and will
peak at age 10.
After age 10 the level of antibodies in our system will gradually decline
The antibodies in our blood will react against any foreign Antigen that is not apart of our own
system
