Sterile Eye is a Norwegian medical videographer. On his blog he shares his "experiences and thoughts on this rather unusual line of work". I find it a fascinating view and hope you will check him out. Here is a recent example in Inner Scents:
"Normal tissue hardly smell at all. .......... Opening the abdominal cavity does not emit any smells, unless there’s some infected parts, necrotic tissue, pierced bowels or gas present.
Cutting the body is not in itself a source of foul scents, but the way it’s cut can cause smell.........."
