aquired immunity
resistance resulting from exposure to an infectious agent
allergen
an allergy-producing substance
antibody
a molecule generated in specific opposition to an antigen
antigen
substance that induces sensitivity or an immune response in the form of antibodies
appendix
worm-like dead-end projection that is attached to the intestine
artificial immunity
immunization; immunity acquired from a vaccination
autoimmunity
literally, immune to oneself
inflammation
redness and irritation caused by injury or abnormal stimulation by a physical, chemical or biologic agent
leukocyte
white blood cell
lymph
fluid that flows through the lymphatic system
lymphatic system
collective, the vessels, nodes and capillaries that carry the lymph and its disease-fighting cells to the areas in which they are needed
lymphocyte
white blood cell in the lymphatic system
macrophage
large phagocyte
microphage
small phagocyte
monocyte
a type of white blood cell
natural immunity
resistance manifested be an individual who has not been immunized; immunity passed from mother to baby
neutrophil
a granulocyte that is that chief phagocytic white blood cell
pathogen
substance that produces disease
phagocyte
white blood cell that clears away pathogens and debris
phagocytosis
process of white blood cells
reaction
an action of a specific antibody on a specific antigen; also, in reference to immune responses, an abnormal or unwanted reaction
spleen
immune system organ that gets rid of damaged red blood cells and reclaims and stores iron
T cell
cells that make up about 80% of lymphocytes; the T denotes their work for the thymus
thymus
immune system gland located behind the sternum
tonsil
collection of lymph tissue; in common understanding, the lingual, phrangyeal and (esp) palatine tonsils
anaphylaxsis
life-threatening reaction to a foreign substance; symptoms include blockage of air passages, decreased blood pressure and generalized edema
hemolysis
change or destruction of red blood cells
Hodgkin lymphoma
chronic malignant disease of the lymph nodes
immunodeficiency
impairment of the immune system
lymphadenitis
inflammation of a lymph node
lymphadenopathy
chronic or excessively swollen lymph nodes; any disease of the lymph nodes
lymphangitis
inflammation of lymph vessels
lymphitis
inflammation of lymph vessels or nodes
lymphedema
swelling of the subcutaneous tissues due to obstruction
lymphoma
tumor of the lymph tissue
lymphopathy
disease of the lymph vessels or nodes
splenitis
inflammation of the spleen
splenomegaly
enlargement of the spleen
splenopathy
disease of the spleen
systemic lupus erythematous
an inflammatory connective tissue disorder with variable features; diffuse erythematous butterfly rash on the face
thymitis
inflammation of the thymus
tonsilitis
inflammation of a tonsil (commonly the palatine tonsil)
antiviral
drugs used to treat various viral infections or conditions
chemotherapy
treatment of malignancies using chemical agents and drugs (usually reserved for treatment of cancer)
corticosteroids
hormone-like preparations used as anti-inflammatory agents; topical agents used for their immunosuppressive and inti-inflammatory properties
lymphangiography
radiography of the lymph system
