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 vessels and nodes are made of lymph tissue, but so are many other parts of the body. One crucial function of lymph tissue is generating and storing white blood cells, the blood cells that fight infection.
