Hematology
Across
- 2. The hemoglobin of sickle cell disease in which there are two normal A chains and two abnormal beta chains that fold poorly, causing the red blood cell to assume a sickle shape under low-oxygen conditions
- 4. Destructive reduction of circulating platelets after normal platelet production
- 6. Cellular excess in the peripheral blood
- 7. Selective growth of bone marrow stem cells into mature erythrocytes.
- 9. Unspecialized (undifferentiated) cells that are capable of becoming any type of blood cell
- 14. Process by which a specific part of the blood is removed by automated blood processing equipment and the remainder is transfused back into the patient (also called hemapheresis or pheresis)
- 17. White blood cell cancer of mature B lymphocytes called plasma cells that secrete antibodies
- 18. Genetic disorder in which a mutation in the gene for the beta chains of hemoglobin causes chronic anemia, pain, disability, organ damage, increased risk for infection, and early death as a result of poor blood perfusion
- 21. The period of greatest bone marrow suppression
- 22. Anemia caused by immunity problems in which individuals form antibodies against their own RBC membranes
- 23. Reddish-purple pinpoint hemorrhagic lesions in the skin
- 24. Clotting disorder causing thrombosis and hemorrhage
- 26. A reduction in white blood cells [WBCs]
- 28. Condition in which there is a deficiency of circulating red blood cells (RBCs) due to impaired cellular regulation of the bone marrow, which then fails to produce these cells
- 29. Condition in which there are lower-than-normal levels of neutrophils in the blood
- 30. The main type of hemoglobin in the fetus, having two normal A chains and two normal gamma chains that bind oxygen more tightly than does hemoglobin A or S
- 31. Spectrum of disorders in which there is reduced or absent production of one or more globin chains, leading to ineffective red blood cell maturation
Down
- 1. The process that dissolves fibrin clot edges with special enzymes to prevent over enlargement of a clot beyond the area where it is needed
- 3. Reduction in the number of circulating platelets from reduced platelet production
- 5. One of the chronic myeloproliferative neoplasms (MPNs) in which there is loss of cellular regulation and excessive proliferation of specific groups of abnormal myeloid cells that have decreased function
- 7. Mature red blood cells (RBCs)
- 8. Blood cancer that results from a loss of normal cellular regulation, leading to uncontrolled production of immature WBCs (“blast” cells) in the bone marrow
- 10. The multistep process of controlled blood clotting, resulting in localized blood clotting in damaged blood vessels to prevent excessive blood loss while continuing blood perfusion to all other areas
- 11. Cancers of the lymphoid cells and tissues with loss of cellular regulation and abnormal overgrowth of lymphocytes
- 12. Anemia that results from insufficient iron in the body
- 13. Anemia resulting from failure to absorb vitamin B12, caused by a deficiency of intrinsic factor (a substance normally secreted by the gastric mucosa), which is needed for intestinal absorption of vitamin B12
- 15. Normal adult hemoglobin with two normal A chains and two normal B chains
- 16. Reduction in the number of red blood cells (RBCs), the amount of hemoglobin, or the hematocrit (percentage of packed RBCs per deciliter of blood)
- 19. Classification of leukemic cells arising from the myeloid pathways; also known as myelogenous, myelocytic, or myeloblastic cells
- 20. Condition in which there is a deficiency of red blood cells, white blood cells, and platelets
- 25. A complex, multistep process by which blood forms a protein-based structure (clot) in an appropriate area of tissue injury to prevent excessive bleeding while maintaining whole-body blood flow (perfusion)
- 27. The total arterial blood flow through the tissues (peripheral perfusion) and blood that is pumped by the heart (central perfusion)
