Show Answers:

  1. cardiovascular system:
    made up of the heart, blood and blood vessels
  2. pericardial sac:
    two parts
  3. fibrous pericardium:
    outer layer
  4. serous pericardium:
    inner layer
  5. epicardium:
     outer most layer
  6. myocardium:
    middle muscular layer
  7. endocardium:
    lines the heart
  8. atria (atrium) (singular atrium):
    the upper chambers of the heart, smaller
  9. ventricle:
    the lower chambers of the heart, larger
  10. septum:
    separates the chambers internally down the middle
  11. superior vena cava:
    Receives blood from upper body
  12. inferior vena cava:
    Receives blood from lower body
  13. pulmonary trunk:
    right and left artery
  14. pulmonary veins (four):
    return oxygenated blood to heart
  15. ascending aorta:
    take oxygenated blood out to body in order, it’s composed of the aorticarch, descending thoracic artery, and the abdominal artery
  16. tricuspid valve:
    (three cusps) Between the right atrium and right ventricle
  17. bicuspid valve:
    (two cusps) Between the left atrium and left ventricle
  18. chordae tendineae:
    which hold them back when the valves are closed and keep them fromgetting blown back into the atria
  19. pulmonary semilunar valve:
    between the right ventricle and the pulmonary trunk where it exits the heart
  20. aortic semilunar valve:
    between the left ventricle and the ascending aorta where it leaves theheart
  21. cardiac cycle:
    both relax while the atria fill, atria contract while ventricles relax and fill, ventricles contract while atria relax
  22. diastole:
    relaxation phase
  23. systole:
    contraction phase
  24. systemic circulation:
    all blood leaving left ventricle (oxygenated), all blood returning to right atrium (deoxygenated)
  25. pulmonary:
    blood flow to lungs for gas exchange
  26. cerebral:
    blood flow to the brain, which uses a lot of resources
  27. fetal:
    between developing fetus and mother
  28. tunica intima:
    innermost layers
  29. tunica media:  
    middle layer
  30. tunica adventitia:
    outer layer
  31. lumen:
    blood vessel cavity
  32. arteries:
    thicker and stronger than veins
  33. arterioles:
    small arteries attach to capillaries
  34. capillaries:
    gas nutrient and waste exchange
  35. venules:
    connect capillaries to veins
  36. veins:
    less elastic than arteries, contain valves
  37. coronary arteries:
    branch off and supply the heart
  38. brachiocephalic artery:
    Right common carotid artery and right subclavian artery
  39. left common carotid artery:
    Left internal carotid artery and left external carotid artery
  40. left subclavian:
    Vertebral artery, axillary artery, brachial artery and radial and ulnararteries
  41. subclavian artery:
    artery becomes the axillary artery
  42. axillary artery:
    which becomes the brachial artery
  43. brachial artery:
    upper arm
  44. radial artery:
    runs along the radius  
  45. ulnar artery:
    runs along the ulna
  46. superficial palmar arch:
    supply the deep palmar arch
  47. deep palmar arch:
    supplies the hand
  48. common iliac artery:
    on each side becomes the external iliac artery
  49. external iliac artery:
    which becomes the Femoral artery
  50. femoral artery:
    becomes the popliteal artery
  51. popliteal artery:
    splits to become the posterior tibial artery
  52. posterior tibial artery:
    and the anterior tibial artery, which feed the
  53. dorsalis pedis:
    feeds the planters arch
  54. plantar arch:
    which supplies the digital arteries
  55. veins:
    Found closer to surface than arteries They all converge with the …
  56. inferior vena cava:
    which both empty into the heart
  57. radial vein
    vein and the ulnar vein form the basilic vein
  58. basilic vein:
    radial vein  vein and the ulnarvein form the brachial vein
