Chapter 9: Lymphatic Flashcards
Acquired immunity
Immunity that is a result of the body developing the ability to defend itself against a specific agent, as a result of having had the disease or from having received an immunization against a disease
Adenoids
Masses of lymphatic tissue located near the opening of the nasal cavity into the phalanx
Pharyngeal tonsils
Edema
The accumulation of fluid within the tissue spaces
Hypersensitivity
An abnormal condition characterized by an excessive reaction to a particular stimulus
Immune reaction (immune response)
A defense function of the body that produces antibodies to destroy invading antigens and malignancies
Immunity
The state of being resistant to or protected from a disease
The individual is said to be “immune”
Immunization
The process of creating immunity to a specific disease
Immunologist
The health specialist whose training and experience is concentrated in immunology
Immunology
The study of the reaction of tissues of the immune system of the body to antigenic stimulation
Immunotherapy
A special treatment of allergic responses that administers increasingly large doses of the offending allergens to gradually develop immunity
Local reaction
A reaction to treatment that occurs at the sit it was administered
Lymph
Interstitial fluid picked up by the lymphatic capillaries and eventually returned to the blood
Once the interstitial fluid enters the lymphatic vessels, it is known as lymph
Lymphadenopathy
Any disorder of the lymph nodes or lymph vessels, characterized by localized or generalized enlargement
Lymph/o
Lymph
Aden/o
Gland
-Pathy
Disease
Lymphocyte
Small, agranulocytic leukocytes originating from fetal stem cells and developing in the bone marrow
Macrophage
Any phagocytes cell involved in the defense against infection and in the disposal of the products of the breakdown of cells
Natural immunity
Immunity with which we are born
Genetic immunity
Pathogens
Disease-producing microorganisms
Path/o
Disease
-Gen
That which generates
Phagocytosis
The process of a cell engulfing and destroying bacteria
Phag/o
To eat
-Osis
Condition
Resistance
The body’s ability to counteract the effects of pathogens and other harmful agents
Susceptible
A state of having a lack of resistance to pathogens and other harmful agents
A person is said to be “susceptible”
T cells
Cells important to the immune response
Mature in the thymus
Upon maturation, the T cells enter the blood and circulate throughout the body, providing defense against disease by attacking to reign and/or abnormal cells
Tonsils
Masses of lymphatic tissue located in the protective rings, just unclear the mucous membrane, surrounding the mouth and back of the throat
Immun/o
Immune, protection
Lymphaden/o
Lymph gland
Lymphangi/o
Lymph vessel
Sarc/o
Flesh
Acquired immunodeficiency syndrome (AIDS)
Involves clinical conditions that destroy the body’s immune system in the last or final phase of a human immunodeficiency virus (HIV) infection
Cytomegalovirus
Large species-specific herpes-type virus with a wide variety of disease effects
Hypersensitivity
Tissue damage resulting from exaggerated immune responses
Hypersplenism
Syndrome involving a deficiency of one or more types of blood cells and an enlarged spleen
Kaposi’s sarcoma
Locally destructive malignant neoplasm of the blood vessels associated with AIDS, typically forming lesions on the skins, visceral organs, or mucous membrane
Lymphoma
Lymphoid tissue neoplasm that is typically malignant, beginning with a painless enlarged lymph node(a) and progressing to anemia, weakness, fever, and weight loss,
Mononucleosis
Usually caused by the epstein-barr virus (EBV)
Benign, self- limiting acute infection of the B lymphocytes
Myasthenia gravis
An auto immune disease in which antibodies block or destroy some acetylcholine receptor sites
Pneumocystis carinii pneumonia (PCP)
Caused by a common worldwide parasite for which most people have immunity if they are not severely immunocompromised
Pneum/o
Lungs
Air
Pneumon/o
Lungs
Air
Sarcoidosis
Systemic inflammatory disease resulting in the formation of multiple small, rounded lesions (granulomas) in the lungs (compromising 90%), lymph nodes, eyes, liver, and other organs
Systemic lupus erythematosus (SLE)
An inflammatory connective tissue, disease, chronic in nature, in which immune complexes are formed from the reaction of SLE autoantibodies and their corresponding antigens
Enzyme-linked immunosorbent assay (ELISA)
Blood test used for screening for an antibody to the AIDS virus
Also be used to test for other diseases, such as Lyme disease
Western blot
Test detects the presence of the antibodies to HIV, the virus that causes AIDS, used to confirm validity of ELISA tests
CT (CAT) Scan
A collection of X-ray images taken from various angles following injection of a contrast medium
Lymphangiogram
X-ray assessment of the lymphatic system following injection of a contrast medium into the lymph vessels in the hand or foot
Angi/o
Vessel
Histo
Histology
