Across
- 1. the amount of blood expelled through the ventricle with each beat
- 4. the hearts main artery which carries nutrient-rich blood away from the heart to the body's cells
- 6. a potentially fatal physiological reaction usually characterized by significant drop in blood pressure, reduced blood circulation, and inadequate blood flow to the tissues; may occur in response to several conditions including illness, injury, hemorrhage, and dehydration
- 10. hearts electrical system consisting of specialized cells within heart muscle that carry an electrical signal which regulates the pumping of the heart
- 12. a woven flexible absorbent cloth applied to a wound
- 14. the smallest of the veins
- 17. infection control guidelines designed to protect workers from exposure to disease spread by contact with blood or other bodily fluids
- 18. tiny cell fragments in blood that aid in clotting
- 21. the rhythmical beating of the heart
- 22. the artery that connects the heart to the lungs
- 23. the yellowish liquid part of blood
- 24. the lower chambers of the heart
- 25. the difference between the diastolic and systolic pressures in the heart
Down
- 2. the percentage of the maximum heart rate that is safe to reach during exercise
- 3. the hearts own system of blood vessels
- 5. a petroleum-based dressing with a thin plastic film designed to keep air and moisture from entering or escaping a wound
- 7. the body system that includes the functions of the heart, blood vessels, circulation, and exchange of gases between the blood and the atmosphere
- 8. blood vessels that carry blood back to the heart
- 9. the output of blood by the heart per minute
- 11. the lowest pressure in the heart; relates to ventricular relaxation
- 13. the upper chambers of the heart
- 15. the smallest of the arteries
- 16. tiny microscopic blood vessels that connect arteries to veins
- 19. the highest pressure in the heart; correlates to ventricular contraction
- 20. the wall separating the left and right sides of the heart
