Voynich's anatomy

[ololololo]

If you think the tube is intestines, then I guess you would think the semicircle bits are the ligaments or fatty deposits, if they are on the outside, or maybe food if it is on the inside? How do you see it?

A stylization of Archimedean pipes, or, as you said, the process of food or feces flowing through, which the author disguised with his favorite scales

What are the two exits to you? Are they the exits from the body or do they go on to other parts?

In any case, the lower part (where the liquid flows out) is most likely the anus.
It is possible that the author could not detail all the details of the intestine, so he made it more schematic.

I think, knowing you have a copy, means that perhaps you could write and ask the person or place who had the original, or someone else who may have a copy, for another look at it, or another copy of the page (hopefully made by someone else), if you couldn't understand it, (i think it would be interesting to check one's copy against someone else's copy, just as we enjoy comparing them all now.) But the lack of notes correcting weird things might mean that these are just things to have? As opposed to things to read or refer to, to use and learn from.

Perhaps... But in the case of VMS, it's done as an assumption, like, "Well, my theory is probably true, but the stupid scribes/authors/artists/alien forces have drawn it incorrectly."
