Across
- 3. lower part of heart
- 5. types, O A B AB
- 8. group of heart cells in the atria, adjusts heart to meet oxygen needs
- 11. Center, sympathetic innervation of the periphery causing vasoconstriction – Relaxation (vasodilatation) due to inhibition (or withdraw) of the VMC
- 12. blood cells, Helps fights disease, produced in bone marrow, larger than but not as many as red blood cells, live longer-months or years
- 13. a cardiovascular diseased cause by the buildup of fatty material in the arteries
- 16. Liquid part of blood, caries nutrients, waste, and chemical messengers
- 17. upper part of heart
Down
- 1. hollow muscular organ that pumps blood throughout the body
- 2. carry blood away from heart
- 3. a one way door which doesn't allow blood to back flow-V shaped-
- 4. narrow blood vessels that are one cell thick so nutrients, oxygen and waster can diffuse through, connects arteries and veins
- 6. system blood heart blood vessels
- 7. carry blood to the heart
- 9. a cardiovascular disease contributed with high blood-pressure
- 10. located in the carotid arch and the aortic arch of the heart. Baroreceptors tell whether the pressure is increased or decreased in the system and sends signals to the brain.
- 14. blood cells, picks up oxygen from lungs and carry it to body cells, produced on bone marrow, contain hemoglobin- iron-containing protein that helps red blood cells carry oxygen, pick up waste from blood cells and carries it away, no nuclei live about 120 days
- 15. Acceleratory Center, sympathetic innervation of the heart causing increase in heart rate and contraction
- 16. Alternating expansion and relaxation of artery walls
