It's convenient to use a military analogy when talking about the immune system---the body's Department of Defense. If we take that analogy one step further, then the lymphatic system is the body's equivalent of soldiers who come in after the battle to mop up and restore some semblance of order.
The lymphatic system cleanses our cells by acting like an internal vacuum cleaner, sucking up unwanted material at the cellular level.
The clear lymph fluid---plasma---is the liquid means used to transport toxic wastes away from the cells and to recycle usable products back into the food chain. The plasma filters out of the bloodstream and accumulates in tiny, thin-walled vessels made up of one-way valves, where it's pumped along-by the contraction of nearby muscles used during the body's activity.
These vessels become clogged with excess proteins or other dead cells when there's a lack of regular exercise. Since muscle contractions of the main pump serve to circulate the plasma, we must exercise if we want to maintain the lymphatic highway of our immune system.
Traveling along this highway are cells that have consumed bacteria, viruses or other foreign material. But infectious intruders can directly invade the lymphatics, too. In any case, before the lymph fluid reenters the bloodstream, it must pass through some lymph nodes, which act as protective filters.
Sometimes the lymph nodes are inadequate, so secondary filters such as the liver and spleen must intercept the invaders and detoxify the blood. The liver also removes foreign material that has penetrated the bloodstream without traversing the lymphatic system.

Humoral Immunity are the guys walkin' the beat, they stick to the streets, alleys, and outdoors (the body fluids).http://youtube.com/user/Kiknskreem
