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

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
Ans: b. Stimulate the release of Na+ (thus increasing urine volume) from
the kidneys
