Question | Answer | Answer | Answer | Answer |
Anemia | Blood disorder characterized by red blood cell, hemoglobin, and hematocrit levels below normal range | | | |
Aplasia | In hematology, a failure of the norm process of cell generation and development | | | |
Disseminated intravascular coagulation(DIC) | Acquired hemorrhage syndrome of clotting, cascade overstimulated lesion, and anticlotting processes | | | |
Erythrocytosis | Abnormal increase in the number of circulating red blood cells | | | |
Erythropoiesis | The process of red blood cell production | | | |
Hemarthrosis | Bleeding into the joint space, a hallmark of severe disease usually occurring in the knees, ankles, elbows | | | |
Hemophilia A | Hereditary coagulation disorder; caused by lack of antihemophilic factor 8, which is needed to convert prothrombin to thrombin through thromboplastin component | | | |
Heterozygous | Having 2 different genes | | | |
Homozygous | Having 2 identical genes, inherited from each parent, for a given hereditary characteristic | | | |
Idiopathic | Cause unknown | | | |
Leukemia | Malignant disorder of the hematopoietic system in which an access of leukocytes accumulates in the bone marrow and lymph nodes | | | |
Leukopenia | abnormal decrease in the number of white blood cells to fewer than 5000 cells/MM 3 due to depression of the bone marrow | | | |
Lymphangitis | Inflammation of one or more lymphatic vessels or channels; usually results from an acute streptococcal or staphylococcal infection and an extremity | | | |
Lymphedema | Primary or secondary disorder characterized by the accumulation of lymph in soft tissue and edema | | | |
Multiple myeloma | A malignant neoplastic immunodeficiency disease of the bone marrow; tumors composed of plasma cells | | | |
Myeloproliferative | Excessive bone marrow production | | | |
Pancytopenic | Deficient condition of all 3 major plot elements(red cells, white cells, and platelets); result from the bone marrow being reduced or absent | | | |
Pernicious | Capable of causing great injury or destruction; deadly, fatal | | | |
Reed-Sternberg cells | Atypical histocytes; large, abnormal, multinucleated cells in the lymphatic system, found in Hodgkin's lymphoma | | | |
Thrombocytopenia | abnormal hematologic condition in which the number of platelets is reduced to fewer than the 100,000/mm3 | | | |
plasma | rbs, wbcs, platelets are suspended in a light yellow fluid | 55% bloods volume | 45% composed of blood cells and platelets | |
3 critical functions of blood | transports oxygen and nutrition to cells and waste product away from cells | regulates acid-base balance (PH)with buffers, regulates body temp | protects the body against infection with special cells and prevents blood loss with special clotting mechanisms | |
Erythrocytes (RBC) | give blood its rich color, constantly producing red bone marrow | m-4.7-6.1 million
w-4.2-5.4 million | concave, actual cell count, classified according to size, shape, color | carries oxygen from the lungs to the cells and carries carbon dioxide away from the cells to the lung |
Erthropoiesis | process of the RBC, depending on several factors | | | |
Most important body functions | transportation and protection | | | |
circulatory system | primary transportation fluid, blood viscous(thick), rbc, wbc, platelets | | | |
lymphatic system | maintain fluid balance, and protect the internal environment | | | |
