  15. upper right and left chamber of the heart
    atrium
  16. membrane lining the cavities of the heart
    endocardium
  17. membrane forming the outer layer of the heart
    epicardium
  18. partition between the right and left atrium
    interatrial septum
  19. partition between the right and left ventricle
    interventricular septum
  20. heart muscle
    myocardium
  21. protective sac encolsing the heart; composed of two layers with fluid between
    pericardium
  22. outer layer of the pericardium
    parietal pericardium
  23. layer colsest to the heart (of pericardium)
    visceral pericardium
  24. fluid-filled cavity between the paricardial layers
    pericardial cavity
  25. lower right and left chambers of the heart
    ventricle
  26. structures that open and close, regulating one way flow of blood
    heart valves
  27. heart valve between the left ventricle and the aorta
    aortic valve
  28. heart valve between the left atrium and left ventricle
    bicuspid/mitral valve
  29. heart valve opening from the right ventricle to the pulmonary artery
    pulmonary semilunar valve
  30. valve between the right atrium and the right ventricle
    tricuspid
  31. valves located at intervals within the lining of veins, esp legs
    valves of the veins
  32. vessels that carry blood away from the heart to the arterioles
    arteries
  33. large artery that is the main trunk of the arterial system branching from the left ventricle
    aorta
  34. small vessels that receive blood from arteries
    arterioles
  35. tiny vessels that join arterioles and venues
    capillaries
  36. small vessels that gather blood from capillaroes into the veins
    venules
  37. vessels tht carry blood to the heart from the venules
    veins
  38. circulation of the blood throughout the body-delivering oxygen and nutrients to tissues.
    systemic circulation
  39. circulation of blood through the coronary blood vessels, delivering oxygen and nutrients to the heart
    coronary circulation
  40. circulation of blood from pulmonary artery through lungs and back to heart thry pulmonary vein; gas exchange
    pulmonary circulation
  41. period of expansion, blood enters relaxed ventricles from atria
    diastole
  42. period of contraction, blood is ejected through the aorta and pulmonary arteries
    systole
  43. normal blood pressure
    normotension
  44. low blood pressure
    hypotension
  45. high blood pressure
    hypertension
  46. sinoatrial node (SA node)
    • the pacemaker, in right atrium, initiates electrical conduction of the heart
    • causes atria to contract and fire conduction impulses to the AV node
  47. atrioventricular node (AV node)
    neurological tissue at the center of heart; receives and amplifies the conduction impulses sent down from the SA node, the AV node sends this impulse to the Bundle of His
  48. bundle of His
    neurological fibers, extend from AV node to the His branches, then to the Purkinje fibers.
  49. Purkinje fibers
    fibers in the ventricles that transmit impulses to the R and L ventricles-causing them to contract.
  50. normal sinus rhythm (NSR)
    regular rhythm of the heart cycle-stimulated by the SA node (60-100 bpm)
