  1. the three layers of the heart are:
    endocardium, myocardium and epicardium
  2. the electrical impulse of the heart is generated by the:
    sinoatrial (SA) node and atrioventricular (AV) node
  3. the electrical activity of the heart is recorded on an:
    electrocardiogram (ECG)
  4. during the phase of _____ the myocardium contracts
    systole
  5. during the phase of _____ the myocardium relaxes
    diastole
  6. the amount of blood pumped by each ventricle in 1 minute is called
    the cardiac output (CO)
  7. the volume of blood in the ventricles at the end of diastole, before the next contraction, is called:
    preload
  8. the peripheral resistance against which the left ventricle pumps is called:
    afterload
  9. the exchanged of cellular nutrients and metabolic end products takes place in vessels called:
    capillaries
  10. the two main factors influencing blood pressure are:
    cardiac output (CO) and systemic vascular resistance
  11. the _________ artery is the recommended site for taking blood pressure
    brachial
  12. when blood pressure is measured, the pressure int he cuff is lowered, and _____ sounds are auscultated
    korotkoff
  13. the term for the difference between the systolic blood pressure and diastolic blood pressure is
    pulse pressure
  14. with increased age, the amount of ______ in the heart increases and the amount of _______ decreases
    collagen; elastin
  15. orthostatic blood pressures are measured while the patient is
    supine, sitting, and standing
  16. the sound generated by turbulent blood flow through major arteries is termed
    murmur
  17. the first heart sound, S1, is associated witht eh closure of the ______ and _______ valves
    tricuspid; mitral
  18. the second heart sound, S2, is associated with closure of the _______ and ______ valves
    aortic; pulmonic
  19. what part of the stethoscope is used to auscultate the first and second heart sounds
    diaphragm
  20. an elevation in which lipoprotein increases risk of CAD
    low-density lipoproteins
  21. an elevation in which lipoprotein decreases risk of CAD
    high-density lipoproteins
