  1. aterial bp
    pressure difference between L and R of heart that product gradient allowing systemic movement of blood
  2. Cardiac output
    CO = SV (stroke volume) x HR (heart rate)
  3. end-diastolic volume
    preload
  4. systemic vascular resistance
    • afterload 
    • determined by radius of arteries and degree of vessel compliance
  5. systolic bp
    peak pressure during cardiac systole
  6. diastolic bp
    lowest pressure during cardiac diastole
  7. SV
    primary factor influencing systolic pressure
  8. SVR
    major determinant of diastolic pressure
  9. mean arterial pressure
    MAP = [(2 x diastolic pressure) + systolic pressure]/3
  10. Angiotensin II produces a what in SVR
    an increase
  11. What does ANP do
    ANP cause the kidneys to increase sodium and water excretion by increasing the glomerular filtration rate
  12. normal lab for bp
    • normal : (S/D) <120/80
    • prehypertension: 120-139/80-89
    • Stage 1 hypertension: 140-159/90-99
    • Stage 2: >160/100
