exam 6 Flashcards
splenomegaly
enlarged spleen
protein produced by B cells to destroy antigens
antibody
Blood cell fragments that help clot blood
thrombocyte
WBC
White blood cells also known as leukocytes. They are less common than RBC. They fight infection.
Granulocytes
basophil eosinophil neutrophil
mononuclear
lymphocyte and monocyte
found in red blood cells and allows them to carry oxygen
hemoglobin
collection of stationary lymph tissues found in neck, armpit, chest, groin, intestine, and lumbar areas.
lymph nodes
T lymphocytes that bacteria and foreign cells by recognizing a cell as foreign and destroying it. They also help B cells make antibodies.
T-cells
Another term for blood clotting
coagulation
malignant tumor of lymphoid tissue in the spleen and lymph nodes. this disease is characterized by lymphadenopathy, splenomegaly, fever, weakness, loss of appetite. The diagnosis often is made by identifying the type of malignant tumor.
Hodgkin lymphoma
these lymphomas such as follicular and large cell are mostly B cell lymphomas and rarely T cell malignancies
Non Hodgkin lymphomas
Enzyme linked immunosorbent assay– test to detect anti HIV antibodies
ELISA
malignant tumor of bone marrow cells
multiple myeloma
the bodies ability to recognize and remember specific antigens in an immune response. lymphocytes (T and B cells) are apart of it. T cells remember and B cells secrete antibodies.
adaptive immunity
Substance that the body recognizes as foreign; evokes and immune response. Most are proteins or protein fragments found on the surface of bacteria, viruses, or organ transplant tissues.
Antigens
protein that forms the basis of a blood clot
Fibrin
Swelling that results when too much fluid from blood leaks out into tissue
Edema
excess iron deposits throughout the body
hemochromatosis
mass of lymphatic tissue in the nasopharynx
adenoids
group of clinical signs and symptoms associated with suppression of the immune system and marked by opportunistic infections, secondary neoplasms, and neurologic problems
AIDS
contains granules that stain the eosin, a red acidic dye. These granules increase in allergic response
eosinophils
excessive bleeding caused by hereditary lack of VIII and IX necessary for blood clotting
hemophilia
EPO
erythropoietin
warfarin
drug given to patient with thromboembolic diseases to prevent the formation of clots
resistance present at birth and is not dependent on previous exposure
natural immunity
exaggerated or unusual hypersensitivity to foreign protein or other substance
anaphylaxis
the stopping of flow of blood
hemostasis
a type of lymphocyte and a component of innate immune system. These cells play a major role in the host-rejection of both tumors and virally infected cells
Natural killer cells
bone marrow in fetuses and children to the age of five that produce erythrocytes, leukocytes and megakaryocytes.
red bone marrow
deficiency in erythrocytes or hemoglobin
anemia
failure of blood cell production in the bone marrow
aplastic anemia
reduction in red cells due to excessive destruction
hemolytic anemia
lack of mature erythrocytes caused by inability to absorb vitamin B12 into the bloodstream
pernicious anemia
hereditary disorder of abnormal hemoglobin producing sickle-shaped erythrocytes and hemolysis
sickle cell anemia
inherited disorder of abnormal hemoglobin production leading to hypochromia
thalassemia
universal donor
type O
chrom/o
color
eosin/o
red, dawn, rosy
erythr/o
red
hem/o
blood
is/o
same, equal
kary/o
nucleus
morph/o
