Yes, but the important question is: how far are we from those limits? Normally the liver has a lot of extra capacity and regrows amazingly well. There are people who live ordinary lives with 75% of their heart muscle dead (the trick is to have the right parts of the heart in order), and you need to loose quite a few percent of the neurons of a brain system to get observable effects. The body is quite fault tolerant.
