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