Can someone explain why the answer is what it is, please. Thinking about this is hurting my head; I don't understand the explanation.
I think this is what you are saying. But to me it seemed like if the volume did not change, but pressure did there would be no work like in an isovolumetric system. But this obviously makes no sense because the heart has to do some work. Wouldn't it seem to be opposite?
@aldol16 Yeah. I didn't think the answer made sense because no volume change means no work. Also, as you stated, the PV diagrams applies to gases because they are compressible unlike liquids, and thus, are able to do work. So basically if this question applied to gases, would the answer be 'No work is done', like originally what I had picked as the answer?
@aldol16 Quick question. Sorry to bring this post back up. But PV diagrams apply to gases only right? Is there a case with PV diagrams for liquids?
So PV diagrams are non-applicable with cardiovascular physiology i.e. stroke work (work done by the ventricle to eject a volume of blood aka stroke volume into the aorta, a diagram of ventricular pressure vs. volume)? I am just asking because there was some confusion with another post I read elsewhere that stated that PV diagrams are applicable in this case. It would seem this type of work is mechanical work, as you said before, or what?
