All of that requires respiration and a working bloodstream as well as a nervous system that works like a human's (or any mammal?).

Basically, because the chloroform worked, we had confirmation that the Zeds physiology was still a) working and b) mostly human. That was later confirmed by Tanya's autopsy of the Little One but does it matter that we knew that way back when?

Hmmmm......

Well, Saul and Angel did see them sleeping as early as chapter 3. I would assume that the need for sleep would imply that their bodies still work similarly to those of normal humans. I doubt that they were certain that the chloroform would work, but just from what they had already seen it was at least a pretty safe bet.
