Across
- 2. the shape of the red blood cell is a sickle shape, which makes the red blood cells clump together
- 8. a layer of cardiac muscle that makes up the middle of the heart
- 9. blockage of the arteries, usually in the legs
- 12. tissue death in the heart muscle resulting from an occluded (obstructed) coronary artery; heart attack
- 16. white blood cell that is involved in fighting infection
- 18. fibrous sac that encloses the heart
- 20. a red blood cell that transports oxygen and carbon dioxide to and from body tissues
- 21. a blood clot that forms within a blood vessel and does not travel through the blood
- 22. blood vessel that connects arterioles with venules
- 26. abnormal sound heard during auscultation of the heart, such as a whooshing sound created by a valve not completely closing
- 28. become abnormally dilated, due to interference with venous drainage or weakness of their walls
- 30. four chambers, two upper (atria) and two lower (ventricles) through which blood flows through the heart
- 32. vessels that convey blood; includes arteries, arterioles, capillaries, venules, and veins
- 34. yellowish liquid containing mostly water, which carries nutrients and hormones
- 36. the innermost layer that lines the four chambers (two atria and two ventricles) and covers the valves of the heart
- 37. a condition of low blood pressure
Down
- 1. disease resulting from reduced blood flow from the heart; characterized by weakness, breathlessness, abdominal discomfort, and edema in the lower extremities
- 3. related to the heart and blood vessels
- 4. muscle contractions occurring due to electrical conduction
- 5. inherited from one’s parents and determined by the presence or absence of an antigen found on the surface of the red blood cell
- 6. major blood vessel
- 7. flaps of tissue located between the heart chambers which allow the blood to flow only in one direction
- 10. blood disorder caused by changes in a gene on the X chromosome
- 11. inherited from one’s parents and determined by the presence or absence of an antigen found
- 13. complete or partial loss of blood flow to brain tissue caused by blood vessel spasms
- 14. a condition in which the arteries of the heart are narrowed, affecting the supply of oxygen and nutrients to heart muscle
- 15. a cell fragment that helps form blood clots to repair injured blood vessels
- 16. a cell that makes antibodies to mark and destroy invading pathogens

- 27. blood vessel that moves blood from body tissues toward the heart
- 29. a distended and weak area in the wall of an artery
- 31. a mass (most commonly a blood clot) that travels through the blood and can become lodged in a blood vessel and obstruct blood flow
- 33. chest pain or discomfort; is characterized by a sensation of squeezing, pressure, heaviness, or tightness in the center of the chest
- 35. abnormal heart rhythm
