Across
- 3. a blood vessel that carries blood away from the heart to other parts of the body
- 7. a tiny blood vessel that connects arteries to veins, facilitating the exchange of oxygen, carbon dioxide, and nutrients, with surrounding tissues
- 8. a test that records the electrical activity of the heart over a period of time using electrodes placed on the skin
- 10. refers to the circulatory system, which includes the heart and blood vessels ( arteries, veins, and capillaries )
- 12. the phase of the heartbeat when the heart muscle contracts and pumps from the chambers into the arteries
- 13. the rhythmic throbbing of arteries as blood is propelled through them, typically felt in the wrist or neck
- 16. the way the hearts electrical impulses travel through the heart muscle, causing it to contract and pump blood
- 17. Pressure the force of blood pushing against the walls of the arteries
- 19. the largest artery in the body, responsible for carrying oxygen-rich blood from the heat to the rest of the body
Down
- 1. the phase of the heartbeat when the heart muscle relaxes and the chambers fill with blood
- 2. the sequence of events that occur during one complete heartbeat. It includes the filling of the heart with blood (diastrole) and the ejection of blood from the heart (systrole)
- 4. the muscular tissue of the heat, responsible for its ability to contract and pump blood throughout the body
- 5. Rate the number of times a person's heart beats per minute
- 6. a noninvasive test that records the electrical activity of the heart over time
- 9. the process of blood delivery to a capillary bed in the biological tissue
- 11. a blood vessel that carries blood towards the heart from other parts of the body
- 14. one of the two upper chambers of the heart
- 15. refers to a lymph node, which is a small, bean-shaped structure that is part of the body's immune system
- 18. refers to an electrode attached to the body to conduct electrical signals from the heart to an electrocardiograph (ECG) machine
