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
Hemolytic
Function of destroying worn out erythrocytes and release their hemoglobin for reuse
Herpes zoster
An acute viral infection characterized by painful skin eruptions that follow underlying route of an inflamed nerve
Hodgkin’s lymphoma
A malignancy for the lymphatic system that is distinguished from non-Hodgkin’s lymphoma by the presence of reed stern berg cells
Immunodeficiency disorder
A condition that occurs when the immune system response in compromised
Immunoglobulin
Antibodies that bind with specific antigens in the antigen antibody response
Immunosuppressant
A substance that prevents or reduces the body’s normal immune response
Immunotherapy
A disease treatment that involves either stimulating or repressing the immune response
Inflections mononucleosis
An infection caused by the Epstein Barr virus that is characterized by fevers a sore throat and enlarged lymph nodes
Infiltrating ductal carcinoma
Breast cancer that starts in the milk duct breaks through the wall of that duct and invades the fatty breast tissue
Interferons
Are produced In Response to the presence of antigens particularly viruses or tumor cells. Interferons activate the immune system fight viruses by stopping g or slowing their multiplication and signals other cells to increase defenses
Lymphadenitis
Inflammation of the lymph nodes
Lymphadenopathy
Any disease process affecting a lymph node
Lymphangioma
A benign tumor formed by an abnormal accumulation of lymph fluid within the tissue
Lymphedema
Swelling of the tissue due to abnormal accumulation of lymph fluid in the tissue
Lymphocytes
Lymphoid cells formed in bone marrow natural killer cells, B cells,and T cells
Lymphoscintigraphy
A diagnostic test that is performed to detect damaged malformations of the lymphatic vessel
Macrophage
A type of leukocytes that surrounds and kills invading cells also remove dead cells and stimulates the action of the immune cells
Metastasis
A new cancer site that results from the spreading process
Metastasize
The process by which cancer spread from one place to another
Myoma
A benign tumor made up of muscle tissue
Myosarcoma
A malignant tumor made of muscle tissue
Opportunistic infection
Caused by a pathogen that does not normally produce an illness in healthy humans
Osteosarcoma
A hard tissue sarcoma that usually involves the upper shaft of long bones pelvis or knee
Rubella
A viral infection characterized by a low grade fever, swollen glands, inflamed eyes and fine pink rash
Sarcoma
A malignant tumor that arises from connective tissue
Spirochetes
A long slender spiral bacteria that have flexible walls and are capable of movement
Splenomegaly
An abnormal enlargement of the spleen
Staphylococci
A group of the 30 species of bacteria that form irregular groups or clusters resembling grapes
Streptococcai
Bacteria that form a chain. Many are harmless however other members of this group are responsible for illness including strep throat
Systemic reaction
Anaphylactic severe response to an allergen
Teletherapy
Radiation therapy administered at a distance from the body that is precisely targeted with the use of three dimensional computer imaging
Toxoplasmosis
A parasite most commonly transmitted from animals to humans by contact with contaminated feces
Varicella
A highly contagious infection caused by the herpes virus varicella zoster also known as chicken pox
