An autopsy is performed by making a Y shaped incision from the shoulders down to the pelvic bone. The abdominal cavity is then exposed and the rib cage is taken out, allowing for removal of the neck and chest organs. These organs are then removed so they can be freely dissected. Having all this information is helpful to determine cause of death, providing an insight into what their organs we're going through to keep that person alive. Having the ability to look at the organs and tissues and run samples freely helps to determine cause of death quicker with more precise diagnose.
