Across
- 2. shortness of breath.

- 4. it is a node that generates an electrical signal that causes the upper heart chamber to contract also known as the cardiac peacemaker.
- 5. in this circuit, blood with oxygen, nutrients and hormones travels from the heart to the rest of the body.
- 6. flap off tissue in the heart and large veins that prevents blood from flowing backwards.
- 8. pointed end of a conical structure.
- 14. thick muscular layer of the heart.
- 16. this blood contains higher concentration of oxygen.
- 17. abnormally rapid heartbeat.
- 19. the pumping center/station of the human body.
- 27. an act or instance of circulating, moving in a circle or circuit, or flowing.
- 28. heart chamber that receives blood returning to the heart from other parts of the body.
- 30. blood vessels that carry blood away from the heart.
- 33. pressure in the artery when the left ventricle is contracting to force the blood into the aorta and other arteries.
- 34. a chamber of the heart that receives blood from an atrium and pumps it to the arteries.
- 35. abnormally high blood pressure.
- 36. blood vessels that carry blood back to the heart.
- 37. swelling from excessive accumulation of serous fluid in tissue.
- 39. of or relating to either of two major arteries supplying blood to the head and neck.
- 42. small vessels that receives blood from the arteries.
- 43. muscular wall that separates the right and left sides of the heart.
- 45. it includes your arteries, veins, and capillaries.
- 46. valve between right atrium and right ventricle.
Down
- 1. removes extra fluid from the body also called water pill.
- 2. this blood contains higher concentration of carbon dioxide.
- 3. liquid portion of blood made up of water, dissolved salts, proteins, and other substances.
- 7. an inflammation of the blood vessels caused by an overactive immune system.
- 9. abnormally slow heartbeat.
- 10. this circuit carries blood without oxygen from the heart to the lungs.
- 11. sac that surrounds the heart.
- 12. smallest blood vessels, materials are exchanged between the blood and the body's cells.
- 13. cells that are primarily responsible for transporting oxygen and carbon dioxide through the body.
- 15. it is a group of conditions that affect your heart muscle, leading to weakened heart squeeze.
- 18. a cardiovascular disease characterized by a sac-like widening of an artery resulting from wakening of the artery.
- 20. cell fragments that work in clotting.
- 21. a blood cell that defends against infection by disease-causing bacteria and viruses.
- 22. a clot that breaks loose and travels through the blood stream.
- 23. closes the left ventricle when it contracts.
- 24. pressure int he artery when the ventricles are relaxing and the heart if filling, receiving blood from the vena cava and pulmonary veins.
- 25. a disease that occurs when blood flow to your brain gets interrupted.
- 26. the rhythmic expansion and recoil of arteries; initiated by the contractions of the ventricles of the heart.
- 29. chest pain with exertion.
- 31. collects deoxygenated blood from the whole body and brings it back to the heart for new oxygen.
- 32. made up of red and white blood cells, plasma and platelets.
- 37. a thin, smooth tissue that makes up the lining of the chambers and valves of the heart.
- 38. small vessels that gather blood from the capillaries into the veins.
- 40. abnormally low blood pressure.
- 41. this circuit provides the heart muscle with oxygenated blood.
- 43. lower cholesterol and lowers the risk of heart attack and stroke.
- 44. complex protein compound.
