- 64. the circulation of blood between the heart and the lungs.
- 65. the second stage of hemostasis, concluding with the formation of the hemostatic plug.

- 72. the middle layer of an anticoagulated blood specimen that has been spun in a centrifuge; contains white blood cells and platelets.
- 73. a disorder that can cause excessive bleeding.
- 74. the middle layer of veins or arteries.
Down
- 1. a cell produced in the bone marrow that fragments into platelets.
- 2. blood in the veins; it is deoxygenated and dark, deep red in color.
- 4. blood in the capillaries; contains both arterial and venous blood and its color is somewhere between bright and deep red.
- 7. a type of white blood cell that is the body’s first defense against illness.
- 9. the largest of the white blood cells; matures into macrophages, which “eat” invading organisms.
- 10. designation for people who do not have Rh factor on their red blood cells.
- 14. the heart valve located between the right atrium and the right ventricle.
- 17. the outer layer of veins or arteries.

- 20. a disorder that can cause excessive clotting.
- 21. the circulation of blood between the heart and the rest of the body (except the lungs).
- 22. a protein associated with blood clotting; fibrinogen is turned into fibrin when injury occurs, creating a mesh with platelets to stop bleeding.
- 23. reaction to injury in a blood vessel causing narrowing of muscular tissue at the site of the injury.
- 25. a type of white blood cell.
- 28. a type of lymphocyte that produces antibodies.
- 30. a tubular device with a plunger that, when pulled, acts to draw in fluid (e.g., blood).
- 32. designation for people who have Rh factor on their red blood cells.
- 33. cells directly.
- 34. a category of short-lived white blood cells including eosinophils and basophils.
- 35. elements the solid portion of blood.
