The Lymphatic System
TONSIL
The tonsils are also part of the immune system.
Because of their location at the
throat and palate, they can stop
germs entering the body through
the mouth or the nose. The tonsils
also contain a lot of white blood cells, which
are responsible for killing germs.
BONE MARROW
Bone marrow is a sponge-like
tissue found inside the bone. That
is where most immune
system
cells are produced
and then
also multiply. These
cells move to
other organs and tissues through the
blood.
SKIN, MUCOUS
MEMBRANES AND
FIRST- LINE DEFENSES
Skin produces oils and secretes other
protective immune system cells. Mucous
membranes line the respiratory, digestive, urinary
and reproductive tracts. These membranes secrete
mucus, which lubricates and moistens surfaces
STOMACH AND BOWEL
Stomach acid kills many bacteria soon after they
enter the body. Humans also have beneficial
(good) bacteria in your intestines that
kill harmful bacteria
The lymphatic system is an interactive network of
lymphoid organs, cells, humoral factors, and
cytokines. Its essential function in host defense is
best illustrated when it goes wrong; underactivity
resulting in the severe infections and tumors of
immunodeficiency, overactivity in allergic and
autoimmune disease (Parkin & Cohen, 2001).
Overall, the lymphatic system is responsible for
keeping the body free from hazardous organisms in
the body.

THYMUS
Located behind the breastbone
above the heart. This gland-like
organ reaches full maturity only
in children, and is then slowly
transformed to fatty tissue. Special types of
immune system cells called thymus cell
lymphocytes (T cells) mature in the thymus.
SPLEEN
The spleen sits in the
upper left of the abdomen,
protected by the rib cage. It
is the largest organ of the
lymphatic system — the circulation of the
immune system. It recycles old red blood
cells and stores platelets (components of
the blood that help stop bleeding) and
white blood cells.
.
LYMPH NODES
Lymph nodes are small
bean-shaped tissues found
along the lymphatic vessels. The
lymph nodes act as filters. Various immune
system cells trap germs in the lymph nodes
and activate the creation of special
antibodies in the blood.
Protect. The body system continuously barricades
these deleterious agents from its framework.
Regulate. Keeping the health balance of the body.
The cells produced by the organs functioning in the
this system performs filtration and extermination
of harmful substances foreign from the body.
Adapt. The body relies on the immune and
lymphatic system’s capability to grow and evolve.
