Across
- 1. The study of the heart and its diseases.
- 4. Specialized fibers that quickly spread the electrical signal through the ventricles to cause a coordinated contraction.
- 6. A fast heart rate.
- 10. Imaging of blood vessels.
- 15. The yellowish liquid component of blood, comprising 90% water.
- 16. blood pressure cuff, measures the pressure of blood against the blood vessels in millimeters of mercury written (mmHg)
- 17. Cell fragments that enable clotting to stop bleeding.
- 18. Hypotension
- 19. The voice box, which connects the pharynx and trachea.
- 24. Cells that transport oxygen from the lungs to body tissues.
- 26. Receives oxygen-rich blood from the lungs.
- 28. Tool used to amplify sounds of the body such as respirations, pulse, or gut sounds.
- 29. The strongest chamber; it pumps oxygen-rich blood to the entire body.
- 30. A slow heart rate.
- 31. Tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged.
- 33. minimum pressure reading, when the heart is at rest (between heart beats) Lower number.
- 35. maximum pressure against blood vessels during contraction of the heart, (when the heart beats) Upper #
- 36. widening of blood vessels, respectively.
- 37. The narrowing of blood vessels, respectively.
- 38. Pumps oxygen-poor blood to the lungs.

- 2. An irregular heartbeat.
- 3. Immune cells that fight infections.
- 5. The natural pacemaker in the right atrium that generates electrical impulses that coordinate the contraction of heart (starts the heartbeat.)
- 7. A blood clot.
- 8. High blood pressure
- 9. Small branches of the bronchi that lead to the alveoli.
- 11. Four one-way valves (tricuspid, pulmonary, mitral, and aortic) ensure blood flows in the correct direction and prevent backflow.
- 12. The main muscle of breathing, located below the lungs.
- 13. Membrane surrounding the lungs to reduce friction.
- 14. The throat, which serves as a passageway for air and food.
- 17. The main windpipe connecting the larynx to the lungs
- 20. One of the two main air tubes branching from the trachea into the lungs.
- 21. Blood rich in oxygen (usually in arteries)
- 22. A "relay station" that delays the signal to allow the heart chambers to fill with blood.
- 23. Blood poor in oxygen (usually in veins).
- 25. Receives oxygen-poor blood from the body.
- 27. Insufficient blood supply to a tissue due to blockage.
- 32. A flap of tissue that covers the trachea during swallowing.
- 34. Hair-like structures that move mucus and debris out of the lungs.
