Across
- 3. an inherited clotting defect caused by absence of a blood clotting factor.
- 4. the cardiac muscle layer of the heart wall.
- 5. a vessel that carries blood away from the heart.
- 8. the arterial blood pressure during ventricular relaxation.
- 11. Shock condition where blood vessels are not adequately filled and circulation cannot continue normally.
- 17. the rhythmic expansion and recoil of arteries resulting from heart contraction; can be felt from the outside of the body.
- 19. signs indicators of general cardiovascular health, such as pulse (heart) rate, blood pressure, respiration rate, and temperature.
- 22. valve two valves set between the atria and ventricles to prevent backflow; includes the mitral (bicuspid) on the left and the tricuspid on the right.
- 25. a condition of having too few platelets.
- 26. Volume a volume of blood ejected by a ventricle during systole.
- 27. slow heart rate, usually defined as a rate under 60 beats per minute.
- 29. ovale opening in the interatrial septum of the fetal heart that shunts blood away from the undeveloped lungs.
- 30. class of white blood cells that lack visible granules in their cytoplasm; includes lymphocytes and monocytes.
Down
- 1. the stoppage of bleeding.
- 2. presence of an abnormally large number of erythrocytes in the blood.
- 6. the percentage of erythrocytes to total blood volume.
- 7. an abnormal, excessively rapid heart rate; over 100 beats per minute.
- 9. hormone that stimulates erythrocyte production; secreted by kidneys.
- 10. Coat the layer of white blood cells in a tube of spun whole blood at the junction between erythrocytes and the plasma.
- 12. reduced oxygen carrying capacity of the blood caused by a decreased number of erythrocytes or decreased percentage of hemoglobin in the blood.
- 13. Clotting the process of stopping bleeding, involving a cascade of steps resulting in fibrin production.
- 14. semilunar valve the major systemic artery; arises from the left ventricle of the heart.
- 15. a specialized substance produced by the body that can provide immunity against a specific antigen.
- 16. clumping of (foreign) cells, induced by cross linking of antigen antibody complexes.
- 18. the rupture of erythrocytes.
- 20. any of a number of proliferative and degenerative changes in the arteries leading to their decreased elasticity and hardening; end stage of atherosclerosis.
- 21. Cycle sequence of events encompassing one complete contraction and relaxation of the atria and ventricles of the heart.
- 23. a fixed clot that develops and persists in an unbroken blood vessel.
- 24. the major systemic artery; arises from the left ventricle of the heart.
- 28. large, multinucleate cells that fragment to produce platelets.
