Respitory System Flashcards
Lymphatic vessels/ducts - lymphangi/o
The capillaries,vessels, and ducts that return lymph from the tissues to venous blood.
Lymph - Lymph/o
The fluid that removes cellular waste products, pathogens, and dead blood cells from tissue
Lymph nodes - lymphaden
Bean shaped structures of the lymphatic system where pathogens and other harmful substances are filtered from the lymph by specialized cells of the immune system
Tonsils and adenoids - tonsill/o and adenoid/o
Lymphoid structures of the lymphatic system that protect then entry to the respiratory system
Spleen - splen/o
A sac like mass of the lymphoid tissue with protective roles in both immune and lymphatic system
Bone marrow - myel/o
Produces lymphocytes which are specialized leukocytes WBC
Lymphocytes - lymphocyt/o
Specialized leukocytes that play important roles in the immune reactions
Thymus - thym/o
A gland located in the upper chest with specialized roles in both the lymphatic and immune system
Allergen
A substance that produces an allergic response in an individual
Anaphylaxis
A severe systemic response to an allergen
Antibody
A disease fighting protein created by the immune system in response to a specific antigens
Antigen
any substance that the body regards as foreign
Antigen antibody reaction
Immune reaction involves binding antigens to antibodies. This reaction labels a potentially dangerous antigen so it can recognized and destroyed
Autoimmune disorder
A condition in which the immune system produces antibodies against the body’s own tissue
Bacilli
Spore forming bacteria
Candidiasis
Yeast infection
Carcinoma in situ
A malignant tumor in its original position that has not yet disturbed or invaded the surroundings
Compliment system
Is a group of proteins that normally circulate the blood in an inactive form. When needed these cells complement the ability of the antibodies to ward off pathogens by combining with them to dissolve and remove pathogenic bacteria
Cytokines
A group of proteins such as interferons and interleukins released primarily by T-cells these cells act as intracellular signals to begin the immune response
Cytomegalovirus
A type of herpes fires found in most body fluids
Cytotoxic drug
Medications that kills damaged cells
