node (pronounced /ˈlɪmf noʊd/) is an organ consisting of many
types of cells, and is a part of the lymphatic system. Lymph
nodes are found all through the body, and act as filters or
traps for foreign particles. They contain white blood cells that
use oxygen to process. Thus they are important in the proper
functioning of the immune system. Lymph nodes also have clinical
significance. They become inflamed or enlarged in various
conditions, which may range from trivial, such as a throat
infection, to life-threatening such as cancers. In the latter,
the condition of lymph nodes is so significant that it is used
for cancer staging, which decides the treatment to be employed,
and for determining the prognosis. Lymph nodes can also be
diagnosed by biopsy whenever they are inflamed. Certain diseases
affect lymph nodes with characteristic consistency and location.
