Across
- 2. A WBC that increases during allergic reactions and parasitic infections.
- 6. Partial Thromboplastin Time A test measuring the intrinsic and common pathway, used to monitor heparin.
- 8. A large agranulocyte that differentiates into macrophages to phagocytize pathogens.
- 10. A white blood cell responsible for immune response (T-cells, B-cells).
- 12. A condition marked by a deficiency of red blood cells or hemoglobin in the blood, reducing oxygen-carrying capacity.
- 15. Blood Count A common laboratory test measuring RBC, WBC, platelet count, hemoglobin, hematocrit, and RBC indices.
- 16. An immature red blood cell that still contains ribosomal RNA, used to assess bone marrow production.
- 19. An abnormally low platelet count, increasing the risk of bleeding.
- 21. Time A test measuring the extrinsic and common pathway of coagulation, used to monitor warfarin.
- 24. Cell Disease An inherited disorder caused by a single amino acid change in hemoglobin, causing rigid, sickled cells.
- 25. The process of formation, development, and maturation of blood cells, primarily in the bone marrow.
- 26. Deficiency Anemia The most common cause of microcytic anemia, often characterized by low MCV and low ferritin.
Down
- 1. The study of blood cells, blood-forming organs, and coagulation in both normal and diseased states.
- 3. Anemia A condition where the bone marrow fails to produce all blood cell types (pancytopenia).
- 4. The ratio of the volume of packed red blood cells to the total volume of blood (expressed as a percentage).
- 5. A granulocyte that releases histamine and heparin during allergic reactions.
- 7. coat The thin, white layer of white blood cells and platelets between the plasma and red blood cells after centrifugation.
- 9. Corpuscular Hemoglobin Concentration The average concentration of hemoglobin in a given volume of packed red blood cells.
- 11. Anemia A form of macrocytic anemia (high MCV) caused by vitamin B12 or folate deficiency, causing impaired DNA synthesis.
- 13. The large bone marrow cell that breaks apart to produce platelets.
- 14. The stoppage of bleeding through vascular spasm, platelet plug formation, and blood clotting.
- 17. A hormone produced by the kidneys that stimulates the bone marrow to produce red blood cells.
- 18. Neutrophil An immature neutrophil; an increase ("left shift") indicates acute infection.
- 20. The most common granulocyte, acting as the primary responder to bacterial infections.
- 21. The liquid portion of anticoagulated blood, consisting of water, electrolytes, proteins, and waste products.
- 22. The iron-containing, oxygen-transporting protein in red blood cells.
- 23. Corpuscular Volume A measurement of the average size of red blood cells.
