the term âalumigraphâ in an article published in the Spring, 2002, edition of. Printmaking Today (vol. 11, no. 1, pp. 28-29), to refer to a rather different process. So, I have decided in fairness to switch to the terms âfoilographâ and. âfoilographyâ instead.
Lymph vessels. Walled, valved structures that carry lymph around the body. Lymph nodes. Small bean-shaped glands that produce lymphocytes, filter harmful substances from the tissues, and contain macrophages, which are cells that digest cellular debris, pathogens and other foreign substances. Major groups of lymph nodes are located in the tonsils, adenoids, armpits, neck, groin and mediastinum.
The lymph nodes do this by filtering lymph and preventing anything that can harm the body from being able to get through. While the pathogen is in the lymph node, white blood cells are produced to destroy the cancer cells, viruses, and bacteria.
