Removing a kidney is like decreasing one resistance of a system with many resistors arranged in parallel. This will cause the net resistance to increase. So...

CO-- Decreases
TPR-- Increases
RBF-- Decreases
Arterial BP-- Increases

Only guessing, whats the right answer?

[ArchivalUser]

good try all of u.explanation of lucid is perfect but pinky is correct in answering.
so CO=decrease
TPR=increase
Total renal bld flow=decrease
arterialBP=no change
but why with increase TPR is not increasing arterial BP?

[ArchivalUser]

Thanks genius for answering. but why no change in BP if TPR is increased?

[ArchivalUser]

wel i didnt get it either.
explanation says removing a kidney doesnt hav lasting effects on arterial pressure.

[ArchivalUser]

yeah i was reading up some studies too. most say that BP in post nephrectomy patients is more or less near normal levels. Ok with the exam just around the corner i think i'll remember it as it is!

Cheers!

[ArchivalUser]

thats the best way to deal with it

[ArchivalUser]

what i thought was, when MAP=CO* TPR ...and when system retirns to normal, BP has to stay same, rt?..body try to maintain the BP?

thanks for the qs
