Across
- 1. blood disorder where the shape of the red blood cells is a sickle shape, causing the red blood cells to clump together
- 9. a layer of cardiac muscle that makes up the middle of the heart
- 15. a blood disorder caused by changes in a gene on the X chromosome; characterized by the inability of blood to clot
- 17. blockage of the arteries, usually in the legs
- 18. a yellowish liquid containing mostly water, which carries nutrients, hormones, and wastes for other body systems
- 21. blood vessel that moves blood from body tissues toward the heart
- 24. a condition in which arteries of the heart are narrowed, affecting the supply of oxygen and nutrients to the heart muscle
- 25. antigen found in red blood cells
- 26. locations to measure the # of times the heart beats per minute
- 27. a white blood cell; involved in fighting infection
Down
- 2. disease resulting from reduced blood flow from the heart; characterized by weakness, breathlessness, abdominal discomfort, and edema in the lower extremities
- 3. a blood clot that forms within a blood vessel and does not travel through the blood
- 4. a cell that makes antibodies to mark & destroy invading pathogens
- 5. chest pain or discomfort; characterized by sensation of squeezing, pressure, heaviness, or tightness in the center of the chest
- 6. complete or partial loss of blood flow to brain tissue caused by blood vessel spasms, intracranial bleeding, and/or obstruction of the blood vessels in the brain
- 7. the four sections (two upper atria and two lower ventricles) through which blood flows through the heart
- 8. muscle contractions occurring due to electrical conduction
- 9. tissue death in the heart muscle, resulting from an occluded (obstructed) coronary artery; heart attack
- 10. a mass(usually a blood clot) that travels through the blood & can become lodged in a blood vessel, obstructing blood flow
- 11. a cell fragment that helps form blood clots to repair injured blood vessels
- 12. a fibrous sac that encloses the heart
- 13. flaps of tissue located between heart chambers; allow the blood to flow in only one direction
- 14. abnormal sound heard during heart auscultation(ex: a whooshing sound from a valve not closing completely)
- 16. a condition of low blood pressure
- 19. veins that have become abnormally dilated due to interference with venous drainage or weakness of their walls
- 20. a distended and weak area in the wall of an artery
- 22. the innermost layer that lines the four chambers and covers the valves of the heart
- 23. a condition of high blood pressure
- 28. a red blood cell; transports oxygen and carbon dioxide to and from body tissues
