Blood, Lymphatic, and Immune Systems Flashcards
antigen
substance that, when entering the body, prompts the generation of antibodies, causing an immune response
autoimmune
type of immune response by the body against its own cells or tissues
capillaries
microscopic blood vessels that connect the ends of the smallest arteries (arterioles) with the smallest veins (venules) of the circulatory system
hematopoiesis
production and development of blood cells, normally in the bone marrow, aka hemopoiesis
immune response
defense function of the body that protects it against invading pathogens, foreign tissues, and malignancies
immunodeficiency
decreased or compromised ability to fight disease or a condition resulting from a defective immune mechanism
interstitial fluid
fluid between cells and in tissue spaces
lymphocyte
type of white blood cell (WBC) found in the lymph nodes, spleen, bloodstream, and lymph that functions in the body’s immune system by recognizing and deactivating foreign substances (antigens)
monocytes
Large WBCs formed in the bone marrow that circulate in the bloodstream and destroy pathogenic bacteria through phagocytosis
oncology
branch of medicine concerned with the study of cancerous growths (malignancies)
pathogens
any microorganism capable of producing disease
transfusion
collection of blood or blood component from a donor followed by its infusion into a recipient

anemia
blood disorder characterized by a deficiency of red blood cell production and hemoglobin, increased red blood cell destruction, or blood loss
aplastic
failure of bone marrow to produce stem cells because it has been damaged by disease, cancer, radiation, chemotherapy drugs; rare but serious form of anemia
pernicious
deficiency of erythrocytes resulting from inability to absorb vitamin B12 into the body, which plays a vital role in hematopoiesis
thalassemia
group of hereditary anemias caused by an inability to produce hemoglobin; usually seen in people of Mediterranean origin
hemophilia
group of hereditary bleeding disorders characterized by a deficiency of one of the factors necessary for coagulation of blood
leukemia
malignant disease of bone marrow characterized by excessive production of leukocytes
acquired immune deficiency syndrome
transmissible infection caused by human immunodeficiency virus (HIV) and associated with suppression of the immune system; characterized by increasing susceptibility to infections, malignancies, and neurological diseases
Hodgkin lymphoma
Malignant disease originating in the lymphocytes (part of the body’s immune system) that occurs most often in young adults and characterized by the presence of unique Reed-Sternberg cells (malignant cells) in the lymph nodes
immunodeficiency
any group of diseases caused by a defect in the immune system and generally characterized by susceptibility to infections and chronic diseases
Kaposi sarcoma
Malignancy of connective tissue, including bone, fat, muscle, and fibrous tissue, that is commonly fatal (because the tumors readily metastasize to various organs) and closely associated with AIDS
Lymphadenitis
Inflammation and enlargement of the lymph nodes, usually result of infection
Lymphedema
deliberating condition of localized fluid retention and tissue swelling caused by a blockage in the lymphatic system that prevents lymph fluid in the upper limbs from draining adequately
mononucleosis
acute infection caused by Epstein-Barr virus (EBV) and characterized by a sore throat, fever, fatigue, and enlarged lymph nodes
multiple myeloma
malignant disease of bone marrow plasma cells (antibody-producing B lymphocytes)
non-Hodgkin lymphoma
a group of more than 20 different types of lymphomas (except Hodgkin lymphoma) that occur in older adults but are not characterized by Reed-Sternmerg cells (malignant cells)
opportunistic infection
any infection that results from a defective immune system that cannot defend against pathogens normally found in the environment
stroke
sudden loss of neurological function, caused by vascular injury (loss of blood flow) to an area of the brain, aka CVA
bone marrow aspiration
removal of small amount of tissue (bone marrow biopsy) to diagnose blood disorders, cancers, or infectious diseases or to gather cells for later infusion into a patient (bone marrow transplantation)
Complete blood count
series of blood tests to determine general health status as screening for infection, anemias, and other diseases, aka CBC
ELISA
Test to screen blood for presence of HIV antibodies or for other disease-causing substances
Lymphangiography
radiographic examination of lymph glands and lymphatic vessels after an injection of a contrast medium to view the path of lymph flow as it moves into the chest region
Tissue typing
technique used to determine the histocompatibility of tissues; used in grafts and transplants with the recipient’s tissues and cells; also known as histocompatibility testing
Western blot
test to detect presence of viral DNA in the blood and used to confirm the diagnosis of AIDS as we as detecting other viruses
blood transfusion
administration of whole blood or a component, such as packed red cells, to replace blood lost through trauma, surgery, or disease
bone marrow transplant
diseased bone marrow is destroyed by irradiation and chemotherapy and replaced from a healthy donor to simulate production of normal blood cells; used to treat aplastic anemia, leukemia, and certain cancers
lumphangiectomy
removal of a lymph vessel
anticoagulants
prevent or delate blood coagulation
immunization
vaccination or injection of immune globulins to induce immunity to a particular infectious disease
immunosuppressants
suppress the immune response to prevent organ rejection after transplantation or slow the profession of autoimmune disease
thrombolytics
dissolve a blood clots
vaccination
introduction of altered antigens (viruses or bacteria) into the body to produce an immune response and protect against disease
