There are strong parallels for balneological imagery (the Balneis tradition, which was quite popular). I'm not saying that Q13 is all (or at all) about bathing, but at least there are some strong visual parallels in other medieval works for some of the pages. Also, medicinal bathing is obviously not anachronistic.
The organ interpretations are anachronistic, apart from the idea that an undulating tube can be intestines. But mostly, we have a series of open pipes and nymphs standing on more or less elaborate architectural features. The idea of the fallopian tubes is based on our vague idea of what modern diagrams of the reproductive system look like. This is completely speculative.
The Balneis angle is also speculative, and I'm not sure to what extent it is relevant, but at least it's based on medieval practices and iconographical parallels rather than fantasy.
