Lymphatic System (LSBS)

The lymphoid system is an element of the body’s immune system, defending
against microorganisms and the destruction of cells or cell parts. The tissues and
organs of the lymphoid system are collections of lymphocytes and related cells.
The term “lymphatic system” in the medical world refers to the body’s complex network of vessels that convey lymph and the organs producing and accumulating lymphocytes (one of two kinds of vertebrate white blood cells). It is
considered the “second” circulatory system and comprises a blindly-ending meshwork of highly permeable lymph capillaries permeating most body tissue and
joining to form larger vessels, resembling veins. It joins the venous system, usually near the heart. Tissue fluid drains into lymph capillaries and passes along the
system. The lymphatic system also includes lymph nodes (ovoid structures on
lymph vessels, responsible for removing foreign bodies from the lymph and for
producing lymphocytes and antibodies) and lymphoid tissue (vertebrate tissue in
which lymphocytes develop—e.g., thymus, embryonic liver, adult bone marrow).
NOTE: The body’s defense operations are a major concern when addressing a
person’s ability to maintain general health and balance within a seriously deteriorating environment. When addressing the issue of immunity, it is important to
look at not only the immune system but also the lymphatic system.
