  1. the three layers fo the heart are
    endocardium, myocardium, and epicardium
  2. the electrical impulse of the heart is generated by th:
    sinoatrial (SA) node and atrioventricular (AV) node
  3. the electrical activity of the heart is recorded on an:
    electrocardiogram (ECG or EKG)
  4. during the plase 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 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 exchnage 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 (SVR)
  11. the ________ artery is the recommended site for taking blood pressure
    brachial
  12. when blood pressure is measured, the pressure in the 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. thethe sound generated by turbulent blood flow through major arteries is termed:
    murmur
  17. the first heart sound, S1, is associated with the closure of the _____ and _______ valves
    tricuspid and mitral
  18. the second heart sound, S2, is associated with the closure of the _____ and _____ valves
    aortic and pulmonic
  19. whawhat part of the stethoscope is used to auscultate the first and second heart sounds:
    diaphragm
  20. regarding lipoproteins, an elevation in which one increases the risk of CAD? Which one is associated with a decreased risk of CAD?
    • Increased risk --> low density lipoproteins
    • Decreased risk --> high-density lipoproteins
