Question

Consider a person standing up from a supine position. How do each of the following parameters change in the first seconds after standing compared to what they were at rest, before they return to normal set point?

Group of answer choices

Total Peripheral Resistance (TPR)

      [ Choose ]            Increase            Decrease            No change      

Venous Return

      [ Choose ]            Increase            Decrease            No change      

End Diastolic Volume (EDV)

      [ Choose ]            Increase            Decrease            No change      

Stroke Volume

      [ Choose ]            Increase            Decrease            No change      

Heart Rate

      [ Choose ]            Increase            Decrease            No change      

Mean Arterial Pressure (MAP)

Answer 1

Total peripheral resistance

Decrease due to increase in the vascular blood to the peripheral that leads to dialtion of the peripheral vessel that lead to decrease in peripheral vascular resistance

Question no 2

Venous return to heart will decrease due to increased gravity as a result venous return decrease

Question no 3

End diastolic volume will decrease as result of increase in reduced venous return.

Question no 4

Stroke volume decrease as a result of reduce in preload

Question no 5

Heart rate increases as a result

Question no 6

The mean arterial pressure will decrease due toess preload
