Target Audience
11th -12th grade

Anatomy & Physiology

Learning Environment
This educational program is designed for
Anatomy & Physiology high school students to
work on their own at a computer. It is
intended for additional instruction after a
class lecture on the topic and a review before
the test.
Objective
Once this PowerPoint activity about blood typing
is complete, the students will be able to
differentiate between the ABO blood types when
given a specific genotype. They will also be able
to appropriately determine the outcome of a blood
type genetic cross when given the parental
genotypes. They will demonstrate this by
answering the Quiz Time questions with 100%
accuracy.

Blood Type
a classification of blood based on
antigens found on the surface of red
blood cells (RBCs)
There are 2 major
blood type systems:
ABO and Rhesus
Type A Blood
The A antigen
can be inherited
from mom
and/or dad. It
appears alone on
the surface of
type A RBCs.
Type B Blood
The B antigen
can be inherited
from mom
and/or dad. It
appears alone on
the surface of
type B RBCs.
Type AB Blood
The A and B
antigens can be
inherited from
mom and/or dad.
They both
appear on the
surface of type
AB RBCs.
Type O Blood
No antigens are
inherited from
mom or dad.
Therefore, no
antigens appear
on the surface of
type O RBCs.
Let’s Check!
What are the four different blood types?
a. A, B, BO, AO
b. A, B, AB, O
c. AB, O, AA, BB
So Close!
Try again.
Way to go!
That’s right!
Blood Transfusions
Blood transfusions make it necessary to
understand the different antigens found on
red blood cells.
A blood transfusion is the process of
transferring blood from one person into
another person’s circulatory system.
Let’s Check!
Why is it important to understand what antigens
are found on the RBC?
a. To know what the RBCs look like.
b. To know if all of your RBCs are the same.
c. To know if a donor and recipient’s RBCs are
compatible
So Close!
Try again.
Way to go!
That’s right!
Blood Transfusions (cont.)
For a blood transfusion to work, the
donated blood must match that of the
recipient’s.
If the blood is not matched properly, then
the immune system of the recipient will
attack the donated blood.
Immune System Response
After birth the immune system makes
antibodies that act against the antigens not
found on the RBCs.
Antibodies are present on the white blood
cells (WBCs).
Watch this video explaining the basics of the
blood transfusion process.
Let’s Check!
Can the blood transfusion donor and the recipient
have different blood types?
a. No
b. Yes
c. Yes, but it’s better if they’re the same.
So Close!
Try again.
Way to go!
That’s right!
Let’s Check!
During a blood transfusion the donor and recipient
are directly connected to one another.
a. Yes
b. No
c. They can be, but it’s better if they aren’t
So Close!

Way to go!
That’s right!

4. Which ABO blood type has two different
antigens on the surface of RBCs?
a. type AB
b. type A
c. type B
d. type O
So Close!
Try again.
Hint: It has two antigens.
Way to go!

5. Which ABO blood type has the A
antigens on the surface of RBCs?
a. type AB
b. type A
c. type B
d. type O
So Close!
Try again.
Hint: They only have one antigen.
Way to go!
That’s right!
6. Which ABO blood type has only the A
antibodies on the white blood cells?
a. type AB
b. type A
c. type B
d. type O
So Close!
Try again.
Hint: They only have one type of antibody.
Way to go!
That’s right!
7. If the blood plasma has antibody A, what
type of blood would the immune system
attack?
a. type A
b. type B
c. type O and type A
d. type O and type B
So Close!
Try again.
Hint: It is antibody A.
Way to go!
That’s right!
8. How are antibodies related to the type of
blood a person can receive?
a. They attack all blood types except those
receivable by a person.
b. They attack the RBCs of the recipient so
they can receive blood from a donor.
c. They have nothing to do with receiving
blood.
So Close!
Try again.
Hint: This is talking about antibodies.
Way to go!
That’s right!
The Genetics of it All
A single gene controls the ABO blood type
system with 3 alleles.
o 2 alleles are dominant (IA and IB)
o 1 allele is recessive (i)
Since there are two dominant alleles, IAIB
genotype expresses codominance.
The Genetics of it All
The gene encodes an enzyme,
glycosyltransferase, that modifies
carbohydrates that make up RBC antigens.
