Medical things I do not know answers to
A friend of mine (hi friend! I doubt you are reading this!) is studying medicine in Europe, and currently getting British citizenship so that she can more easily work in Europe forever and ever. (Her current plan is to be a pathologist in the south of France, a plan which I support very much on both sides.)
She regularly tells me weird medical facts, most of which I forget. I now know, however, that the spleen ruptures easily because it’s got a sort of open circulatory system. I find this incredibly disturbing, though I am not sure why. We also discussed pulse oximeters, because they are cool (unsurprisingly, they are about light absorbtion differences on oxygenated vs unoxygenated blood; surprisingly, they use two wavelengths). We have been unable to come to a conclusion about whether they would read accurately if placed on my gnarly finger (which has poor circulation). I intend to ask if I ever have a chance, though I would much prefer not to.
We also don’t know what precisely happens if you don’t pee for too long. I say things like “I have to pee so badly my bladder’s going to explode”, but I do not believe my bladder will actually explode. I would like to find out, unless of course I am wrong and my bladder would literally explode, in which case I am far happier not knowing.
