Understanding the lymphatic system
The lymphatic system consists of organs, ducts, and nodes. It transports a watery clear fluid called lymph. 
This fluid distributes immune cells and other factorsthroughout the body. It also interacts with the blood circulatory system to drain fluid from cells and tissues.
The lymphatic system contains immune cells called lymphocytes, which protect the bodyagainst antigens (viruses, bacteria, etc.) that invade the body. See more on lymphocytes below.  It is abnormal cells of this type that cause lymphoma.
Main functions of the lymphatic system
| "tocollect and return interstitial fluid, including plasma protein to the blood, 
and thus help maintain fluid balance,  |
| to defend the body against disease by producing lymphocytes,  |
| toabsorb lipids from the intestine and transport them to the blood."  |

Lymph organs
Include the bone marrow, lymph nodes, spleen, and thymus. Besides providing a home for lymphocytes (B-cells andT-cells), the  ducts of the lymphatic system provide transportation for proteins, fats, and other substances in a medium called lymph.
Lymph nodes: "Human lymph nodes are bean-shaped and range in sizefrom a few millimeters to about 1-2 cm in their normal state. 

They may become enlarged due to a tumor or infection. White blood cells are located within honeycomb structures of the lymph nodes.Lymph nodes are enlarged when the body is infected due to enhanced production of some cells and division of activated T and B cells. 

Lymph
"Means clear water and it is basically the fluid andprotein that has been squeezed out of the blood. The lymph is drained from the tissue in microscopic blind-ended vessels called lymph capillaries. 
These lymph capillaries are very permeable, and becausethey are not pressurized the lymph fluid can drain easily from the tissue into the lymph capillaries. 
As with the blood network the lymph vessels form a network throughout the body, unlike the...
