Questions and Answers
  • 1. 
    The membrane that covers the outside of the heart.
  • 2. 
    The muscular wall of the heart, the thickest of the three layers of the heart wall, it lies between the inner layer (endocardium) and the outer layer (epicardium)
  • 3. 
    The membrane lining the inside of the heart.
  • 4. 
    Blood vessel expansion and contraction caused by the blood pumped through them; calculated as the number of expansions occurring per minute.
  • 5. 
    The force exerted in the arteries by blood as it circulates. It is divided into systolic (when the heart contracts) and diastolic (when the heart is filling) pressures.
  • 6. 
    Blood vessels that carry blood away from the heart to the body, does not have valves.
  • 7. 
    Blood vessels that carry blood from the body back to the heart, have valves.
  • 8. 
    One cell thick blood vessels between arteries and veins that distribute oxygen-rich blood to the body.
  • 9. 
    Smallest veins.
  • 10. 
    Smallest arteries.
  • 11. 
    Represent the Atrial depolarization.
  • 12. 
    Represents the Ventricle depolarization.
  • 13. 
    Represents the ventricular repolarization.
  • 14. 
    Composed of simple, squamous epithelium called the endothelium. Rests on a connective tissue membrane that is rich in elastic and collagenous fibers.
  • 15. 
    Makes up the bulk of the arterial wall. Includes smooth muscle fibers, which encircle the tubes, and a thick layer of elastic connective tissue.
  • 16. 
    Consists chiefly of connective tissue with irregularly arranged elastic and collagenous fibers. This layer attaches  the artery to the surrounding tissues. Also contains minute vessels (vasa vasorum-vessels of vessels) that give rise to capillaries and provide blood to the more external cells of the  artery wall.
  • 17. 
    Runs the entire length of the lower extremity and is the longest vein in the body.
  • 18. 
    Inefficient and rapid heart contraction caused by disruptions to the nerve impulses.
  • 19. 
    Heart contraction rate abnormalities, which may manifest as a rate that is too slow (bradycardia) or to fast (tachycardia)
  • 20. 
    The noise heard between normal heart sounds, due to the flow of the blood through a heart valve.
  • 21. 
    The number of contractions of the heart in one minute. It is measured in beats per minute (bpm) When resting, the adult human heart beats at about 70 bpm (males and 75 bpm (females), but this rate varies between people.
  • 22. 
    The volume of blood being pumped by the heart in a minute. It is equal to the heart rate multiplied by the stroke volume.
  • 23. 
    The amount of blood ejected by the ventricle of the heart with each beat usually stressed in milliliters. (ml)
  • 24. 
    The hollow area within the blood vessel.
  • 25. 
    Tissue flaps inside a vein or the heart that prevent the backward flow of blood. Valves open as blood moves through them and close under the weight of blood collecting in the vein due to decreased pressure of gravity.
