Section 37.2 The Immune System
Before you read the section, fill out the triple entry vocabulary journal (chart below) 1 point for
definition, one point for picture, memory aid, phrase or sentence.
Word in Context
One method of defense is
phagocytosis. . . the
process by which
phagocytic cells surround
and internalize the foreign
microorganisms. (p. 1085)
Complement
proteins enhance
phagocytosis by helping the
phagocytic cells bind better
to pathogens, activating the
phagocytes and enhancing
the destruction of the
pathogen’s membrane, . . .
(p. 1085)
Virus-infected cells secrete
a protein called
interferon. (p. 1085)
Lymphocytes are a
type of white blood cell that
is produced in red bone
marrow. (p. 1086)
Antibodies are proteins
produced by B lymphocytes
that specifically react with a
foreign antigen. (p. 1086)
B lymphocytes, often called
B cells, are located in all
lymphatic tissues and can
be thought of as antibody
factories. (p. 1086)

In the lymphatic tissues,
such as the lymph nodes,
the macrophage, with the
processed antigen on its
surface, binds to a type of
lymphocyte called a
helper T cell. (p. 1088)
Activated cytotoxic
T
cells destroy pathogens
and release chemicals called
cytokines. (p. 1088)
Memory cells are
long-living cells that are
exposed to the antigen
during the primary immune
response. (p. 1089)
Immunization, also
called vaccination, is the
deliberate exposure of the
body to an antigen so that a
primary response and
immune memory cells will
develop. (p. 1089)
While you
read pages 1084 to 1091, fill out the foldable that you created with the directions
on page 1075. Be sure to
USE
the vocabulary words from the front page of this
handout.
After reading, answer 3 of the 6 questions:
1. Compare specific and nonspecific immune responses.
2. Describe the steps involved in activating an antibody response to an antigen.
3. Make an illustration demonstrating passive and active immunity.
4. Describe the structure and function of the lymphatic system.
5. Why is the destruction of helper T cells in HIV infection so devastating to SPECIFIC
immunity?
6. Compare the role of helper T cells and cytotoxic T cells in the specific immune response.
