week 12 Flashcards
an abnormal activation of the proteins involved in blood coagulation, causing small blood clots to form in vessels and cutting off the supply of oxygen to the distal tissues.
Disseminated intravascular coagulation (DIC)
Substance, recognized as harmful to the host that stimulates formation of antibodies in an immunocompetent individual.
antigen
overproduction of platelets, leading to thrombosis or bleeding in the bone marrow or increased destruction of platelets in the blood vessels (intravascular) or liver (extravascular). A common sign of thrombocytopenia is the development of pinpoint hemorrhages called petechiae that appear on the lower leg.
thrombocytopenia
any disease of the lymph nodes
Lymphadenopathy
monospot
nonspecific rapid serological test for the presence of the heterophile antibody, which develops several days after infection by Epstein-Barr virus, the organism that caused infectious mononucleosis.
sepsis
presence of bacteria or their toxins in the blood; also called septicemia or blood poisoning.
localized accumulation of blood, usually clotted, in an organ, space, or tissue due to a break in or severing of a blood vessel.
hematoma
dissolve blood clots by destroying their fibrin strands (typically used to break up thrombi in coronary, pulmonary, and cerebral arteries).
thrombolytic
Lymphadenopathy
Any disease of the lymph nodes
enlargement of the spleen
splenomegaly
antigen
Substance, recognized as harmful to the host that stimulates formation of antibodies in an immunocompetent individual.
ANA
Test to identify antibodies that attack the nucleus of the individual’s own body cells (auto-antibodies)
(also known as Hodgkin lymphoma) a malignant disease of the lymph system primarily the lymph nodes, usually remains only in neighboring nodes, it may spread to the spleen, GI tract, liver or bone marrow.
Hodgkin disease
DVT
Deep vein thrombosis
blood clot that forms in a vein deep in the body. Blood clots occur when blood thickens and clumps together.
schilling test
test used to diagnose pernicious anemia by determining if the body properly absorbs vitamin B 12, through the digestive tract.
