Lymph-node definitions

In anatomy, lymph nodes are considered to be part of the immune system. Their responsibility is to protect the body from infections, bacteria and disease. Lymph nodes do this by producing white blood cells, scientifically referred to as lymphocytes. They filter out harmful things that enter the body such as bacteria, viruses, and dead tissue and eliminate it from the body in an attempt to make the body healthy again. When one of these things enters the body, the immune system is activated to fight against it and the lymph nodes swell and they begin to produce large numbers of white blood cells. There are approximately 500 to 700 lymph nodes that are scattered throughout various locations in the human body.

(anatomy, immunology) Small oval bodies of the lymphatic system, distributed along the lymphatic vessels, that are clustered in the armpits, groin, neck, chest and abdomen. They act as filters, with an internal honeycomb of connective tissue filled with lymphocytes and macrophages that collect and destroy bacteria, viruses and foreign matter from lymph. When the body is fighting an infection, these lymphocytes multiply rapidly and produce a characteristic swelling of the lymph nodes.
