Cardiovascular System
Across
- 5. regulates the flow of blood between the right ventricle and the pulmonary arteries
- 12. the innermost layer of the heart that lines all chambers and valves
- 14. the lower chamber of the heart that contains deoxygenated blood
- 15. receives deoxygenated blood from the rest of the body
- 17. The amount of blood pumped by each ventricle in ONE minute.
- 18. Tiny cell fragments (platelets) that are responsible for clotting damaged blood vessels to prevent blood loss.
- 21. the upper chamber of the heart that contains deoxygenated blood
- 23. Red blood cell responsible for transporting oxygen to the body's tissues.
- 26. The fluid matrix that makes up 55% of blood composition.
- 30. the movement of blood between the heart and the lungs
- 31. The amount of pressure exerted on the arteries during systole and diastole.
- 32. Large vessels that carry oxygenated blood AWAY from the heart.
- 33. Pressure exerted by the contraction of the heart muscle.
- 36. Small vessel that transports oxygenated blood into the capillary bed.
- 37. Specialized tissue that regulates the contraction of the ventricles.
Down
- 1. The number of times the heart beats per minute.
- 2. transports deoxygenated blood from right ventricle to lungs
- 3. White blood cells responsible for identifying and fighting infection.
- 4. receives deoxygenated blood from the cephalic and thoracic regions
- 6. transports oxygenated blood to the whole body
- 7. Type of leukocyte that contains lobe-shaped nuclei and contains visible granules.
- 8. the lower chamber of the heart that contains oxygenated blood
- 9. the muscular part of the heart
- 10. Type of leukocyte that has spherical or kidney-shaped nuclei, with no visible granules.
- 11. the movement of blood from the heart through blood vessels to the rest of the body and back to the heart
- 13. A drop in pressure due to the relaxation of the heart as it is filling with blood.
- 16. transports oxygenated blood from lungs to the left atrium
- 19. regulates the flow of blood between the right atrium and right ventricle
- 20. ECG wave(s) that occurs as atria repolarize, and ventricles depolarize causing a ventricular contraction.
- 22. Large vessel that transports deoxygenated blood back to the heart.
- 24. ECG wave(s) that appears when ventricles become repolarized, signaling the end of a heart beat.
- 25. ECG wave(s) that occurs when the AV node depolarizes both atria causing them to contract.
- 26. the sac that encloses the heart to provide moisture and protection.
- 27. Cardiac pacemaker that regulates the contraction of the atria.
- 28. Extensions of the AV node that are embedded in the ventricles.
- 29. Tiny vessel responsible for providing oxygen and nutrients to tissues, and taking CO2 and waste away from the tissues.
- 31. regulates the flow of blood between the left atrium and left ventricle
- 32. regulates the flow of blood between the left ventricle and the aorta
- 34. Small vessel that takes CO2 and waste away from the capillary bed.
- 35. the upper chamber of the heart that contains oxygenated blood
