Description

the tissues and organs (including lymph nodes, spleen, thymus, and bone marrow) that produce and store lymphocytes (white blood cells that fight infection) and the channels or vessels that carry the lymph fluid. The entire lymphatic system is an important part of the body’s immune system. Invasive cancers sometimes get into the lymphatic vessels and spread (metastasize) to lymph nodes.
