The body

During our lecture on the body I found Andres Serrano's morgue series very interesting, especially the "Death by Rat Poison" and "Fatal Meningitis II". I did not like the ones that were blatantly depicting "death" and the bloody body.  After looking at his work, I started exploring other art work about death and art involving the dead body. While doing this I came across picture of body farms and crime scene photos. What intrigued me was whether or not these scientific photos that are taken, while not thinking about art, could they still in fact be referred to as art? If not, why? Because they are taken out of context or not posed?
