lymph the clear fluid that bathes each cell and transfers needed substances and wastes back and forth between the blood and the cells
lymph vessels vessels that receive lymph from the lymph capillaries and circulate it to the lymph nodes
lymph nodes Bean-shaped filters that cluster along the lymphatic vessels of the body. They function as a cleanser of lymph as wells as a site of T and B cell activation
macrophages Found within the lymph nodes, they are phagocytes that destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.

spleen Produces blood cells, destroys damaged blood cells, stores blood cells
thymus gland An endocrine gland located in the upper mediastinum that assists the body with the immune function and the development of antibodies. As part of the immune response it secretes a hormone, thymosin, that changes lymphocytes to T cells.
tonsils oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion; also called palatine
appendix a vestigial process that extends from the lower end of the cecum and that resembles a small pouch
cytokines chemicals released by the immune system that attack infections and communicate with the brain to elicit anti-illness behaviors
lymphokines which are produced by the T cells, direct the antigen-antibody response by signaling between the cells of the immune system
monokines cytokines primarily produced by monocytes and macrophages
interleukins proteins that stimulate the growth of B or T lymphocytes and activate specific components of the immune response
non specific immunity defenses that stop the invasion of pathogens; requires no previous encounter with a pathogen
specific immunity the third line of defense. the body's way of fighting off specific things that invade your body
acquired immunity Formation of antibodies and lymphocytes after exposure to an antigen
natural immunity immunity to disease that occurs as part of an individual's natural biologic makeup
phagocytosis process in which extensions of cytoplasm surround and engulf large particles and take them into the cell
pyrexia fever
inflammation a response of body tissues to injury or irritation
interferons Antiviral proteins secreted by T cells
natural killer cells A type of white blood cell that can kill tumor cells and virus-infected cells; an important component of innate immunity.
immunoglobulins Bind with specific antigens in the antigen-antibody response
humoral immunity specific immunity produced by B cells that produce antibodies that circulate in body fluids
cell-mediated immunity immunity against abnormal cells and pathogens inside living cells
active immunity a form of acquired immunity in which the body produces its own antibodies against disease-causing antigens
passive immunity short-term immunity caused when antibodies produced by other animals for a pathogen are injected into the body
dyscrasia an abnormal or physiologically unbalanced state of the body
anemia a deficiency of red blood cells
acute posthemorrhagic anemia RBC deficiency caused by blood loss
B12 Deficiency -Pernicious anemia: macrocytic anemia, muscle weakness, neurological distrurbances
-neither B12 or Folate will clear up macrocytic but if B12 deficient this can be potentially very dangerous
-vegans takes long time
