Immune Response

State Standards
Organisms have a variety of mechanisms to combat disease. As a
basis for understanding the human immune response:
a. Students know the role of the skin in providing nonspecific
defenses against infection.
b. Students know the role of antibodies in the body's response to
infection.
c. Students know how vaccination protects an individual from
infectious diseases.
d. Students know there are important differences between
bacteria and viruses with respect to their requirements for
growth and replication, the body's primary defenses against
bacterial and viral infections, and effective treatments of these
infections.
e. Students know why an individual with a compromised immune
system (for example, a person with AIDS) may be unable to
fight off and survive infections by microorganisms that are
usually benign.
f.Students know the roles of phagocytes, B-lymphocytes, and Tlymphocytes in the immune system.

lymph, air, & blood.
 Lymphocytes-special white
blood cell that acts as an
antibody to attack specific
antigens.
 B cells-produce and
secrete antibodies.
 T cells-Coordinate immune
defenses by killing cells on
contact.
Key Plays
 Antigen-any substances
that is foreign to your body
(ex. Viruses, bacteria,
toxins, & transplant
tissues).
 Antibody-disease fighting
protein created by immune
system when foreign
substance is present.
 Antigen-antibody
reaction-binds antigens to
antibody's to help fight the
foreign substance in the
body.

being resistant to a specific
disease.

 HIV: transmitted through
blood; destroys Immune
System cells.
 Diabetes: affects insulin
producing cells of the
pancreas.
 Sickle cell anemia: red
blood cells turn into moon
like shape, and bunch up,
which causes clotting.

Routine
There are many things you can
do to enhance the ability for
your body to fight infection:
 Washing hands
 Food safety
 Don’t share needles
 Safe sex
 Live healthfully (eat right,
drink water, exercise, sleep)

There are other factors that
influence the bodies
ability to respond to
foreign invaders including:
 Age
 Heredity
 Opportunistic infection (A
pathogen that normally
doesn’t cause a problem,
but leads to disease in a
person with a weakened
immune system.
