Cardiovascular System
Across
- 3. x-ray imaging of arteries after injection of contrast via a catheter into the aorta or an artery
- 5. Local widening of an arterial wall
- 7. High Blood pressure
- 8. Valve that separates the Left atria from the left ventricle
- 10. arm
- 12. Smooth layer of endothelial cells that lines the interior of the heart and heart valves
- 14. Decreased blood flow
- 17. Beat of the heart as felt through the walls of arteries
- 18. Valve that separates the Right atrium from the Left ventricle and form a one-way passage designed to keep the blood flowing in only one direction
- 19. heart
- 20. vein
Down
- 1. Echoes generated by high-frequency sound waves produce images of the heart
- 2. Inflammation of the membrane (pericardium) surrounding the heart
- 4. Large blood vessels that carry blood away from the heart; lined with connective tissue, muscle tissue, and elastic fibers with an innermost layer of epithelial cells (endothelium)
- 6. Measures blood pressure or the force that the blood exerts on the arterial walls
- 9. Walls that are only one endothelial cell in thickness; carry nutrient-rich oxygenated blood from the arteries and arterioles to the body cells; allow passage of O2 and nutrients out of the bloodstream and into cells; allows CO2 to get back to venules
- 11. X-ray imaging of blood vessels after injection of contrast material
- 13. Thinner than arteries; conduct blood (that has given up most of its O2) toward the heart from the tissues
- 15. Abnormal heart rhythms (dysrhythmias)
- 16. yellowish plaque, fatty substance
