The immune system is
a network of many interdependent cell types that
collectively protect the body
from bacterial, parasitic, fungal, and viral infections
and from the growth of tumor cells. The immune system's
job is a complicated process that involves a coordinated
effort of its many components throughout your body. All
cells of the immune system are initially derived from
the bone marrow. These cells include T lymphocytes,
natural killer cells, B cells, polymorphonuclear (PMN)
leukocytes, macrophages and dendritic cells.
Bone marrow derived stem cells
differentiate into mature cells or into
precursors of cells that migrate out of the bone marrow
to mature elsewhere. B cells, natural killer cells, PMNs,
and prothymacytes (immature T cells) are produced
by the bone marrow as well as red blood cells and
platelets. The thymus produces mature T cells that are
released into the blood stream. The spleen is an
immunological filter that captures foreign materials
passing through it. |

In the bloodstream, migratory macrophages and dendritic
cells present antigens to the T-cells to initiate an
immune response. B cells become activated and produce
large amounts of antibody. Lymph nodes filter lymph and
are found throughout the body. They are mostly composed
of T cells, B cells, dendritic cells and macrophages.
Antigens are filtered out of
the lymph fluid in the node before the lymph is returned
to the circulation. The
captured antigens are presented to the T and B cells
initiating an immune response.

Prolonged stress and poor
nutrition have been shown in countless studies to
suppress immune system function. This
suppressive effect is recognized by scientific
consensus. Unfortunately, each of these factors are a
part of our normal lives and for all practical purposes
not avoidable.
