THE LYMPHATIC SYSTEM, a
vital part of the immune system is a network of organs, vessels and tissues
that work together to move a colorless, watery fluid (lymph) back into the
circulatory system ( the bloodstream).
After the skin, the LS is the second line of defense against
foreign invaders such as viruses and bacteria. Not only it blocks bacteria from entering the body, it
can also remove those harmful ones that evaded the blocking. In addition, the
LS removes excess fluids from the body and reduces swelling/inflammation.
When the lymphatic system cannot sufficiently drain the lymph
fluid, swelling occurs, most often in
the arms and legs.
The protein molecules that are not filtered out start to
accumulate underneath the skin. This is the earliest sign of lymphedema. The
symptoms develop slowly. In fact the apparent symptom of swelling will not be
present yet. Even though the limb looks presumably normal on the outside, the
extra water will pull into the affected area and cause heaviness.
The lymphatic system organs include the bone marrow, thymus and
lymph nodes which keep a healthy balance of fluids throughout the body. By
eliminating waste and abnormal cells from the body, trapping pathogens before
they can cause infection, it defends the body against a myriad of illnesses.
Unlike the heart which pumps blood throughout the circulatory
system, the lymphatic system does not have a central engine or pump. Instead
the LS works through pressure, meaning
your lymph fluid primarily moves when you do. When you don't move, it doesn't
move much, either. Thus, increased circulation including increased blood flow
and the flow of lymph fluid is critical for removing waste from the body.
So, get up and move every hour. Take a short walk around your
house or add some stretches while sitting at your desk. The more movement you
make, the better your lymphatic system will function.
