It may be different, I'm not sure really, I might test it once I get this whole thing going... How thin? What would that make up in terms of volume?

I'm interested in "standard" volume of the sack, which is not equal to amount of serose fluid (which is in it initially). The substitute fluid would be of greater density than water, forcing it to exit first through the top (the tube must be at the very top fot that to work). I can also try...

I don't think I'll be able to get access to a CAT scanner... Okay, new development... It seems that I'll have to do this whole thing in situ. So the sac will have to remain in the body. Here's the idea. I'd enter a plasic tube through the topmost part of the sac. Then I'd introduce a...

Can I? :confused: Should I? :biggrin: Well, if we say that the height of a heart would be ~12cm (and would be as close to the surface as it can be), the hidrostatic pressure on the heart would be ~1 Pa, right? Given the fact that the atmspheric pressure is about 100 kPa, that would be...

How would that effect the results? Hidrostatic pressure would be depending only on the height of submerged heart, right? p=ρ*g*(surfaceToHeartBottom-surfaceToHeartTop) So if I were to slant each heart so that their effective height would be the same, I'd get consistent results, right? But on...

That seems like it would all work. However, there are several thing I'd like you to tell me: Where can I get a pressure sensor that would fit in the heart and how much would it cost? Would hidrostatic pressure of the water in bath have any effect on the results(I'm a bit rusty on physics, I...

But the tissue is elastic, so I can't get constant results... Yep.

I know both are valid approaches, however, I'm interested in the techincal aspect of it. It's easy to measure the volume I inject into the tissue, but how do I measure how much did the tissue strecth? So the tissue we are talking about is pericardial sack. It wraps around the heart and...

I have to measure the size of a cavity of a animal body(s). What is more important I need to measure it on several bodies and compare the results. The cavity is small and contains liquid. That liquid can be extracted and that sets the volume of cavity to 0. It's important to note that the...
