Chapter 6 Lymphatic and Immune systems Flashcards
Lacteals
Structures of lymphatic system that absorb the fats that cannot be transported by the bloodstream
Antigen
Any substance that the body regards as being foreign
Lymphocytes
Leukocytes made in bone marrow as stem cells
B cells
Produce antibodies transform to be plasma cells to produce antibodies
T cells
Origin Thymus,
Cytokines
Group of proteins released by T cells
Interferons
Produced in response to the presence of antigens (type of cytokine)
Interleukins
Direct B and T cells to divide and proliferate
Tonsils
3 pairs Nasopharyngeal, palentine, and lingual
Adenoids
Nasopharngeal tonsils
Thymus
Lympoid tissue above heart
Vermiform Appendix
proper name for appendix
Spleen
Filters microorganisms from blood, Forms lymphocytes and monocytes, hemolytic
Pathogens
Disease-producing microorganisms
Allergens
Substances that produce allergic reactions
Toxins
Poisonous or harmful substances
Malignagt cells
Potentially life-threatening cancer cells
Phagocytes
Monocytes, macrophage, dendritic cells
Monocytes
Leukocytes that provide against many infectious organisms
Macrophage
Surrounds and kills invading cells and remove dead cells
Dendritic cells
Patrol body searching for antigens
Complement system
Group of proteins that normally circulate in the blood
immun/o

onc/o
Tumor
lymphadenitis
Imflammation of the lymph nodes
Lymphaden
Lymph node
Lymphadenopathy
Any disease pretaining to the lymph node/s
Lymphangioma
Benign tumor formed by an abnormal collection of lymphatic vessels
Lymphoscinitgraphy
Diagnostic test that is perfomred to detect damage or malformations to lymphatic vessels
Lymphedema
swelling of tissues due to an abnormal accumulation of lymph fluid within the tissues
Bioimpedance spectroscopy
Non invasive method of diagnosing lymphedema
Localized allergic response
Redness itching, burning where the skin came in contact with the allergen
Systemic reaction (anaphylaxis)
Severe response to an allergen
Allergen-specific immunoglobulin E
Blood test that is sometimes used to determine whether a person is allergic to a particular substance
Severe combined immunodeficiency
Inherited condition in which abnormalities in the immune system
HIV
Damages/kills T cells
AIDS
Final stage of HIV
Kaposi’s Sarcoma
Cancer associated with HIV
ELISA
Blood test to look for HIV, Lyme disease and other infectious conditions
