You are looking at a new synthetic cadaver that's now being used by medical students. Instead of operating on humans or animals, medical students can now play doctor with these really freakishly real looking ones.

"It (the synthetic cadaver) has a heart that beats and blood flows. It has a liver that can make bile, so you can imagine, procedural-wise, this is profound.
Or are they from the set of Walking Dead?
