The lymphatic system plays an important role in the immune system. It is made up of lymph nodes, lymph vessels, the spleen, thymus, and bone marrow. The lymph nodes and spleen act as filters to catch harmful pathogens and produce white blood cells that fight off viruses, bacteria, and other foreign invaders. Diseases of the lymphatic system include lymphoma, leukemia, and infections.

1. Lymph
(Endocrine/Immune)
System
This one is super important…

2. Lymph (Endocrine/Immune)
System
 The immune system is made up of many
different cells, organs, tissues and
substances within your body.
 Each aid in eliminating foreign organisms
from your body and protecting you from
various diseases and illnesses.
 These foreign organisms come in the form
of viruses, bacteria, parasites and fungi.
They are known as “microbes.”

3. First Line of Defense – The Skin
 The skin is thick and very hard to penetrate
and produces a variety of substances that
are harmful to invaders.
 The eyes, nose, and mouth are protected by
fluids or sticky mucus that capture harmful
attackers.
 The respiratory tract has cilia, tiny hairs that
remove particles.
 Intruders that get as far as the stomach are
up against a sea of stomach acid that kills
most of them.

4. Second Line of Defense – White
Blood Cells
 There are several types of immune cells,
each possessing specific duties and
characteristics. Several travel through the
body killing foreign substances as they
find them.
 Others patrol the gastrointestinal tract
lining and blood vessels, safeguarding
particular organs.

5.  The lymphatic system, which includes the
lymph nodes, the spleen, bone marrow
and thymus gland, produces these cells
and transports them throughout the body.
 Lymph nodes and the spleen serve as
filters designed to keep harmful organisms
out of the blood stream. Most immune
cells are produced in the bone
marrow, the thymus or the spleen.

6. Lymph (Endocrine/Immune)
System
 Lymph Nodes - Controls against invaders
such as bacteria and viruses
 Maintains/produces white bloods cells (B
cells, T cells) to battle against foreign cells in
the body. Prevents major illnesses from
taking over the body

7. Diseases/afflictions of the
lymphatic system
 Lymphoma (cancer)
 Leukemia (abnormal WBC)
 Any other infections
 acne
