  1. A recording of the electrical changes in the myocardium during a cardiac cycle.
    Electrocardiogram
  2. Wave corresponding with the initial deflection that corresponds to the depolarization of atrial fibers leading to atrial systole.
    P-wave
  3. Wave that is slowly produced by electrical charges that accompany ventricular repolarization, which ends the ECG pattern.
    T-wave
  4. Second deflection which occurs in the ventricle which causes a greater electrical charge than that of the atria.
    QRS Complex
  5. Indicates the time for the cardiac impulse to travel from the SA node through the AV node.
    PQ Interval
  6. Tenth cranial nerve which allows parasympathetic stimulation of the heart.
    Vagus Nerve
  7. Nerves that join SA and AV nodes and allows sympathetic fibers to reach the heart.
    Accelerator Nerves
  8. Reflexes that control the balance between sympathetic and parasympathetic effects on the heart.
    Baroreceptor Reflex
  9. Portion of the medulla oblongata that regulates the heart.
    Cardiac Control Center
  10. Sensory receptor that detects changes in pressure.
    Baroreceptor
  11. Strong, elastic vessels adapted for carrying the blood away from the heart under high pressure.
    Arteries
  12. Small branches of an artery that communicates with a capillary network.
    Arterioles
  13. Layer of epithelial cells that forms the inner lining of blood vessels and heart chambers.
    Endothelium
  14. Decrease in the diameter of a blood vessel.
    Vasoconstriction
  15. Increase in the diameter of a blood vessel.
    Vasodilation
  16. Postganglionic visceral efferent fibers innervating smooth muscles of vessel walls.
    Vasomotor Fibers
  17. Vessels that carry blood from a capillary to a vein.
    Venules
  18. Open and close to let the blood flow in only one direction between the heart chambers.
    Valves
  19. Blood vessels, including small arteries, arterioles, and meta arterioles that form the major part of the peripheral resistance to blood flow.
    Resistance Vessel
  20. Vessel that carries blood towards the heart.
    Vein
  21. Blood vessels that hold the major portion of the intravascular blood volume (the veins.)
    Capacitance Vessel
  22. The passage of blood directly from arteries to veins, without going through the capillary network.
    Atriovenous Shunt
