Lesson 11 Flashcards
allergen
substance that causes an allergic reaction
autoimmunity
action of antibodies against ones own body
humoral immunity
type of immunity formed by antibodies
immunity
ability to resist a disease
immunization
process of increasing resistance to a disease
immunoglobulins
proteins that act like antibodies
lingual
tonsils found at the back of the tongue
lupus
a chronic inflammatory autoimmune disease
lymph
watery fluid in the lymphatic system
lymphadenitis
inflammation of the lymph nodes and glands
lymphoma
a tumor of the lymphatic system; usually malignant
natural immunity
immunity with which a person is born
spleen
lymph organ situated below and behind the stomach
tonsillitis
infection and swelling of the tonsils
acquired immunity
immunity as a result of exposure to a disease
acquired immunodeficiency syndrome (AIDS)
a potentially fatal disease causing suppression of the immune system
active acquired immunity
two types, natural and artificial acquired immunity
adenoids
pair of glands composed of lymphoid tissue, found in the nasopharynx; also called pharyngeal tonsils
anaphylaxis
severe and sometimes fatal allergic reaction; anaphylactic shock
artificial acquired immunity
type of immunity acquired as a result of an injection of vaccine, antigen, or toxoid
automimmune disorder
a condition that causes destruction of the body’s own tissues
cellular immunity
the body’s ability to resist infections, provided by T lymphocytes
cytokines
in the class of interleukins (part of the immune response), it is a protein produced by damaged tissue and white blood cells; interferon is a type of cytokine
germinal center
area found within the lymph node that produces the lymphocyte
Guillain-Barre syndrome
an autoimmune disease that attack the nerves that control the muscles in the legs, or sometimes in the arms and upper body
Hodgkin’s disease
specific type of cancer in the lymph nodes
Human Immunodeficiency Virus (HIV)
the causative agent of AIDS
hypersensitivity
an abnormal response to a drug or allergen
infectious mononucleosis
contagious disease caused by Epstein-Barr virus; sometimes called the kissing disease
lacteals
specialized lymph vessels in the villi of the small intestine that absorb digested fats and transport them to the circulatory system
lymph nodes
structures that produce lymphocytes and filter out harmful bacteria
lymph vessels
structures that transport excess tissue fluid back into the circulatory system
lymphatic system
system of vessels and nodes that supplement the blood circulatory system and carry lymph, nodes and organs produce lymphocytes to destroy invading bacteria
lymphedema
swelling of the tissue due to an abnormal collection of lymph
lymphokines
chemicals released by T lymphocytes during the immune response, help cellular immunity by stimulation activities of monocytes and macrophages
macrophage
a cell that removes dead organisms and foreign substances by phagocytosis
natural acquired immunity
immunity to a disease that results from having the disease and recovering
passive acquired immunity
borrowed immunity, has a temporary effect
Peyer’s patches
also known as aggravated lymphatic follicles found in walls of the small intestines; they produce macrophages
right lymphatic duct
the lymphatic duct that receives lymph from the right side of the body
scleroderma
disease that results in thickening of the skin and blood vessels
Sjogren’s syndrome
the most prevalent of autoimmune diseases, it affects the moisture glands of the body; symptoms include dry eyes or mouth or other body systems
thoracic duct (left lymphatic duct)
lymphatic duct that receives lymph from the left side of the body
tonsils
mass of lymph tissue in the back of the throat that produces lymphocytes
trabeculae
needlelike bony spicules within cancellous bone that contributes to the spongy appearance; their distribution along lines of stress adds to the strength of the bone
