Exam 14: Intro to Blood & Lymphatics (Basic Terms)
| Term | Definition |
|---|---|
| Anemia | condition characterized by reduction of red blood cells, a deficiency of hemoglobin and hematocrit in the blood, or an increased destruction of red blood cells. Reduction leads to decreased O2 carrying capacity. |
| Aplasia | (Aplastic Anemia) failure of the normal process of cell generation and development. |
| Disseminated Intravascular Coagulation (DIC) | over stimulation of the normal clotting and clot dissolution processes in response to disease or injury, including septicemia, obstetrical complication, malignancies, tissue trauma, transfusion reaction, burns, shock, and snake bites. Mad thick! |
| Erythrocytosis | abnormal increase in the number of circulating red blood cells and also increased production of granulocytes and platelets. |
| Hemarthrosis | bleeding into a joint space. |
| Hemophilia A | absence of anti-hemophilic factor VIII; essential for conversion of prothrombin to thrombin through intrinsic clotting pathway. |
| Heterozygous | having two different genes |
| Homozygous | having two identical genes inherited from each parent for a given hereditary characteristic. |
| idiopathic | cause unknown |
| Leukemia | malignant disorder of the hematopoietic system in which an excess of leukocytes accumulates in the bone marrow and lymph nodes. |
| Leukopenia | low white blood cell count |
| Lymphangitis | inflammation of one or more lymphatic vessels or channels that usually results from an acute streptococcal or staphylococcal infection in an extremity. |
| Lymphedema | primary or secondary disorder characterized by the accumulation of lymph fluid in soft tissue, resulting in edema. |
| Multiple myeloma | malignant neoplastic immunodeficiency disease of the bone marrow |
| Myeloproliferative | excessive bone marrow production of myeloid cells (includes RBC, platelets, granulocytes and agranulocytes). Does not include B and T cells. |
| Pancytopenic | reduction or absence of all three major blood elements (red blood cells, white blood cells and platelets) from the bone marrow. |
| Pernicious | a condition capable of causing great injury, destruction, or death unless treated. |
| Reed-Sternberg cell | - atypical macrophages (phagocytes living in tissue) consisting of large, abnormal, multi-nucleated cells in the lymphatic system found in Hodgkin's disease. These cells increase in number and replace normal cells. |
| Thrombocytopenia | platelet count below 100,000 mm3. |
