The Lymphomas

Abstract

The lymphatic system, with its vessels and nodes, is found throughout the whole body. The lymphoid tissue is concentrated particularly in the nodes and in the spleen. Certain cells can take up particles of foreign protein, e.g. bacteria and vital dyes, a process called phagocytosis. Although found in different organs they collectively are called the mononuclear phagocyte system and the lymph nodes which contain such cells form part of this system, the lymphoreticular system.
