Definition of Immune System
 Protect
your body from diseases
 Protected by White Blood Cell
 Body system of organs, tissues, cells,
and cell products
HOW DOES IT WORK?????


You can get a
vaccination that
protects you from
diseases.
An antigen is any
substance that elicits
an immune response,
from a virus to a sliver
Parts of the Immune System

Fluid System of the body


There are two main fluid systems in the body: blood and lymph.
Innate Immunity System
Immunity that occurs naturally as a result of a person's genetic
constitution or physiology and does not arise from a previous
infection or vaccination.

Phagocytes- a cell that attracts adheres to, engulfs, and ingests
foreign bodies

Adaptive and Acquired Immunity System

Come in two major types: B cells and T cells.
B Cell----------T Cell

B cells


produced in the stem cells of the bone
marrow; they produce antibody and oversee
humoral immunity
T cells

non-antibody-producing lymphocytes which
are also produced in the bone marrow but
sensitized in the thymus and constitute the
basis of cell-mediated immunity.
White Blood Cell
Role in fighting attacking
antigens
Phagocytes
Ingest microbes, other cells and foreign particles
Killer T-cell
Kill the body’s own cells that between invaded by
the viruses or bacteria. Prevents the bug from
reproducing.
Helper T-cell
Stimulate the b cells to make antibodies, and help
killer cells develop.
Supressor T-cell
Emerge from the wilderness bearing surface
maker.
B-cell
React against invading bacteria or viruses by
taking proteins called antibodies.
How does Aids effect immune
system?

Aids is sexually transmitted disease. It
turns off the immune system. Once the
system is off, disease will easily get into
your body.
