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