An increase in arterial blood pressure during systole would cause -
A) a reduction in stroke vol.
B) an increase in the velocity of blood ejection from the ventricles
C) an increase in stroke vol.
D) a reduction of ventricular afterload
E) a decrease in arterial pressure during diastole




  #2

d? or a?


  #3

C.increase in stroke volume


  #4

a reduction in stroke vol. - increase stroke volume
B) an increase in the velocity of blood ejection from the ventricles - nothing wrong with velocity
C) an increase in stroke vol. - excess sodium increase plazma volume->increase stroke volume
D) a reduction of ventricular afterload -increse
E) a decrease in arterial pressure during diastole- will increase excess sodium->vasoconstriction
The answer is C


  #5

The immediate result would be a decrease in stroke volume. Increased afterload (arterial blood pressure as blood is ejected from the ventricle during systole) reduces stroke volume.


  #6

decrease in str vol... due to increaed afterload this in turn will INCREASE preload


  #7

So what is the answer? I think it has to be decrease in stroke volume.


  #8

My answer is A simply because there is resistance to the flow of blood leaving the left ventricle....therefore the decrease in stroke volume.


  #9

Needs to be A...this question appears to ask what happens immediately during the increased afterload (since it says during systole), and that is the only one that makes sense.
