Question | Answer |
---|---|
the average human has __ of blood | 5 quarts |
iron, B12, folic acid, & protein are all raw materials required for | blood synthesis within the marrow |
erythropoiesis is regulated by | erythropoietin |
etiologic classification of anemia might be | blood-loss related |
anemia caused by folic acid deficiency can be secondary to | a poor diet |
anemia caused by bone marrow damage is initially managed with | blood transfusion |
can be acquired through mechanical trauma secondary to an enlarged spleen or by insertion of an artificial heart valve | hemolytic anemia |
hemochromatosis can eventually lead to | organ damage |
patient's medical history & physical exam, complete blood count, reticulocyte count, & bone marrow study are used to | evaluate & diagnosis anemia |
is a complication of polycythemia | increased blood viscosity |
nodes of the lymph system serve as | filters |
enlarged, tender, and inflamed lymph nodes secondary to the spread of an infection into the lymphatic channels | lymphadenitis |
localized infection, systemic infection, lymphoma, & metastatic tumor can all be indicated by | swollen lymph nodes |
Individuals who have had a ___ develop problems with the immune system | splenectomy |
decrease in hemoglobin or red cells or both | anemia |
lymphocyte that differentiates into plasma cells and is associated with humoral immunity | B lymphocyte |
cell that contains numerous variable-sized granules that stain intensely purple with basic dyes. See also eosinophil | basophil |
cell whose cytoplasm is filled with large, uniform granules that stain intensely red with acid dyes | eosinophil |
virus that causes infectious mononucleosis | Epstein-Barr virus |
precursor cell in the bone marrow that gives rise to red blood cells | erythroblast |
humoral substance made by the kidneys that regulates hematopoiesis | erythropoietin |
type of hemoglobin containing two alpha and two gamma chains, which is able to take up and release oxygen at much lower PO2 than in adult hemoglobin | fetal hemoglobin |
oxygen partial pressures | PO2 |
genetic disease characterized by excessive iron absorption, leading to accumulation of excessive amounts of iron in the body, causing organ damage | hemochromatosis |
oxygen transport protein within red cells composed of an iron-porphyrin complex combined with a protein chain | hemoglobin |
anticoagulant obtained from the liver | heparin |
Hodgkin disease is one type of | lymphoma |
abnormally small number of leukocytes in the peripheral blood | leukopenia |
mononuclear blood cell produced in lymphoid tissue that takes part in cell-mediated and humoral immunity | lymphocyte |
lymphoma is a neoplasm of | lymphoid cells |
abnormal red cell precursor resulting from vitamin B12 or folic acid deficiency | megaloblast |
leukocyte having a kidney-shaped nucleus and light blue cytoplasm; a phagocytic cell that forms part of the reticuloendothelial system | monocyte |
leukocyte having a multilobed nucleus whose cytoplasm is filled with fine granules | neutrophil |
macrocytic anemia caused by inability to absorb vitamin B12 as a result of inadequate secretion of intrinsic factor by gastric mucosa | pernicious anemia |
small pinpoint hemorrhage caused by decreased platelets, abnormal platelet function, or capillary defect | petechia |
component of the blood; a roughly circular or oval disk concerned with blood coagulation | platelet |
increased number of red cells | polycythemia |
may be caused by some types of chronic heart or lung disease | secondary polycythemia |
may be due to marrow erythroid hyperplasia of unknown causes | primary polycythemia |
young red cell that can be identified by special staining procedures | reticulocyte |
type of lymphocyte associated with cellmediated immunity | T lymphocyte |
deficiency of platelets | thrombocytopenia |
