They are widely distributed throughout the body along the lymphatic pathways where they filter the lymph before it is returned to the blood.Lymph nodes are not present in the central nervous system.There are three superficial regions on each side of the body where lymph nodes tend to cluster.ymph nodes are small bean-shaped structures that are usually less than 2.5 cm in length. They are widely distributed throughout the body along the lymphatic pathways where they filter the lymph before it is returned to the blood.
It is the role of these nodes to filter the lymph before it can be returned to the circulatory system. Although these nodes can increase or decrease in size throughout life, any nodes that has been damaged or destroyed, does not regenerate. 1  Afferent lymphatic vessels carry unfiltered lymph into the node. Lymph nodes also trap and destroy cancer cells to slow the spread of the cancer until they are overwhelmed by it. 2  Efferent lymphatic vessels carry the filtered lymph out of the node so that it can continue its return to the circulatory system.
