Introduction:
For this assignment I aim to explain and describe the function of the organs in the lymphatic system
as well as the potential disorders of the lymphatic system and their possible corrective treatments.
As per my criteria, we were given the choice to pick between two disorders of the lymphatic system.
The choice that we were given was between Lymphatic Filariasis and Hodgkin Lymphoma, to be our
focus to provide a detailed case study of my chosen lymphatic disorder.
The lymphatic disorder that I chose was Lymphatic Filariasis, so that is what this assignment and case
study will focus on.
The reason I picked Lymphatic Filariasis over Hodgkin Lymphoma is because is globally considered a
Neglected Tropical Disease(NTD). Which interests me since, according to the CDC, they are diseases
that affect more than a billion people all over the world. These diseases mainly affect the poorest
people in the world- They are serious bacterial, viral and parasitic diseases that heavily impair
cognitive and physical development as well as contribute to a huge amount of mother and child
death and illness, and since many people who are affected by these diseases are very poor, it means
that these diseases heavily affect their ability to farm or make a living. Neglected Tropical Diseases
are said to trap poor people into a cycle of disease and poverty, which is why I think it’s a very
important topic to research.
What role does the lymphatic system play in our bodies?
The lymphatic system, which is also known as the body’s sewerage system, is responsible for the
process of maintaining our body tissues fluid levels by removing the fluid that leaks out of our blood
vessels. Our lymphatic system plays an important role in making sure our specific and general
immune system responses are optimally functioning.
Our lymphatic system contains a huge sprawling network of organs, tissues and vessels across our
entire body that work in tandem to locomote a colourless watery type of fluid which is known as
lymph back into your bloodstream.
Parts of the Lymphatic System:
, (Pictured: A diagram of the Lymphatic System from my.clevelandclinic.org.)
Appendix
The appendix is a small pouch that contains lymphoid tissue, which has the capability of destroying
bacteria before it has the chance to breach the intestine wall during absorption. The appendix is also
populated with “good bacteria” that is used to repopulate the guy after an infection.
Peyer’s Patches
Peyer’s Patches are lymphatic tissues which have the function of monitoring and destroying bacteria
in the intestines, described as “small masses” in the mucous membrane lining your small intestine.
Bone Marrow
The bone marrow is the spongy soft tissue inside of certain bones, like the breast and hip bone that
produces red and white blood cells alongside platelets.
Tonsils and Adenoid
The Adenoid and Tonsils are organs that trap pathogens that come from the air you breathe and the
food you eat, these are regarded as the first line of defence for your body in the fight against foreign
invaders
