Across
- 2. Small terminal fibers of the pacemaker cells in the heart that extend from the Bundle of His
- 5. These blood vessels have the smallest diameter; there are approximately 10 billion of them in our body
- 6. This term describes the size of the blood vessel, where the friction between blood and the inner surface of the vessel is inversely proportional to this term.
- 8. This factor changes the solute concentration to adapt to the local metabolic changes
- 9. These are large blood vessels that form by multiple venules, bringing oxygen-poor blood back to the blood
- 14. This term describes the bulk flow to and from the tissue, which occurs when the net pressure is positive
- 17. This can be seen in EKG; this component represents the electrical depolarization of the atria
- 18. During exercise, 88% of the blood flow to this tissue
- 20. This fluid can be found in the space outside of blood vessels that helps bring nutrients and oxygen to the blood
- 21. This term describes the bulk flow to and from the capillaries, which occurs when the net pressure is negative
- 22. This is a thin membrane outside of the heart protects the heart with pericardial fluid
- 24. One of the two mechanisms that capillary exchanges materials, where substances in the blood move independently down the concentration gradient
- 25. When this system is activated, the permeability of K+ increases
Down
- 1. This neurotransmitter helps mediate the parasympathetic system
- 3. These are large blood vessels that carry oxygen-rich blood from the heart to the organs & body cells
- 4. This value is determined by heart rate and stroke volume
- 7. This effect in blood caused by heart damage can lead to heart failure
- 10. When this system is activated, the heart rate slows down
- 11. This mechanoreceptor relays information about blood pressure; they are sensitive to changes in blood pressure to help regulate it
- 12. When the blood pressure is high, above 140/90 mmHg
- 13. One of the two mechanisms that capillary exchanges materials, where plasma flows in and out through the pores in the capillary wall
- 15. This neurotransmitter helps mediate the sympathetic system
- 16. This is an abnormal heart sound due to defective valve function
- 19. The number of heartbeats per unit of time, it is often measured in beats per minute
- 23. The innermost layer of lining in the interior of the heart's chamber
