Anybody well versed in rat dissection?

[Anatopism]

Actually, I'll just add the photos. Sorry a couple of them are blurry. Camera decided it didn't like the shiny bits in the rat. What I specifically was looking for was a sign of hemorrhaging, somewhere, anywhere in the rat.

Not that I think anybody will raise a fuss here on a snake forum, where rodents are regularly fed off or euthanized, I still feel I should add: I did NOT kill this rat, it was found dead, as were several others. A live rat was taken to the vet today for a necropsy, to provide the freshest sample possible. She died 5 minutes after arriving at the vet, was packaged up, and shipped to the lab. I understand very well that I am not a vet, and I openly admit I have little experience in dissection, or proper diagnosis based off of a dissection - I've decided to do one in an attempt to visually see what's going on in my colony, to hopefully learn something, or be able to connect any info I find with the lab results of a necropsy.

ON to the details...
-I'm guessing the rat has been dead between 6-8 hours based on the last time they were checked, and because rigor mortis has already set in. It's been about 60*F all day.
- I didn't notice any blood where it shouldn't be - leaking or dried up anywhere. But this is also why I want others to take a look. See anything I don't see that is concerning? Colors that aren't normal? I'm not sure if the white-ish discoloration on the lungs is normal, or if it coincides with the following:
- Once I cut away the rib cage, I did notice quite a bit of milky-gray fluid, but again, no blood. I do not know if this is something that has happened after death, or if it is fluid built up in the lungs, perhaps a sign of pneumonia?


Feel free to take a look...
