a small molecule that will not evoke a specific immune response unless it is combined with other serum proteins, in which case, a severe reaction may occur
|
hapten
|
|

immunity
|
|
a disease that may be transmitted from one person to another via some type of specific organism such as a bacteria or virus

|
|
a response of the immune system that results in influx of cells and other chemicals to fight a foreign challenge
|
inflammatory response
|
|
a large collection of lymph nodes located in the groin

lingual tonsils
|
|
a thin plasma-like liquid formed from interstitial or extracellular fluid that bathes the tissues of the body
|
lymph
|
|
round or bean shaped structures interspersed along the course of lymph vessels, which filter the lymph and serve as a source of lymphocytes
