Just a quick note to make those unaware aware of The Visible Human Project. They’ve sliced a frozen body up in very thin pieces and photographed each piece. Below is a section through the chest; you can see the heart, lungs, and the spinal column among other things. On the homepage there is an animated ‘travel’ through the body from head to toe.
Of course, there are ethical questions surrounding using data from the project in research. The body belonged to a prisoner given the death penalty. Questions such as Should society, and more specific, should science, benefit from killing prisoners? If one is against the death penalty, is research based on The Visible Human Project still ok? (See Norwegian medical magazine here for discussion.)
