preload?
a. Venous return during diastole
,b. End systolic volume
c. Total peripheral (systemic) resistance
d. All of the above are primary factors of preload Right Answer
- c. Total peripheral (systemic) resistance
Which of the following statements are INCORRECT
a. The mean arterial pressure is the average force of pushing blood
through the systemic circuit.
b. The pulse pressure is the difference between systolic and diastolic
pressures
c. A decrease in aortic compliance increases its stiffness and thus
can lead to an increase in pulse pressures

aorta is termed the:
a. Ejection fraction

c. Preload
d. Afterload Right Answer - d. Afterload
Natriuretic peptides act by:
a. Stimulates secretion of Na+ (and thus decreases urine volume)
from the kidneys
b. Stimulated the release of Na+ (thus increases urine volume) from
the kidneys
c. Increases vascular smooth muscle contraction (vasoconstriction)
d. Stimulates increased heart rate, contractility, and cardiac output
Right Answer - b. Stimulate the release of Na+ (thus increasing
urine volume) from the kidneys
