used. In the Western world, embalming of the body is a standard part of preparation. This is intended to temporarily preserve the corpse throughout the funeral process. Mummification Mummification is the drying bodies and removing of organs. The most famous practitioners were ancient Egyptians. In the Egyptian practices, bodies are embalmed using resins and organs are removed and placed in jars. Bodies are then wrapped in bandages and placed in tombs, along with the jars of organs. Many nobles and highly ranked bureaucrats had their corpses embalmed and stored in luxurious sarcophagi inside their funeral mausoleums. Pharaohs stored their embalmed corpses in pyramids or the Valley of the Kings. However, the Chinchorro mummies of Chile are to date the oldest mummies on Earth. The Chinchorro mummification process included the Black Mummy technique, as well as the Red Mummy technique.

Diseased or necrotic body parts Certain conditions such as necrosis can cause parts of the body such as limbs or internal organs to die without causing the death of the individual. In such cases the body parts are usually not given a funeral. Surgical removal of dead tissue is usually necessary to prevent gangrenous infection. Surgically removed body parts are typically disposed of as medical waste, unless they need to be preserved for cultural reasons, as described above. Conversely, donated organs or tissue may live on long after the death of an individual. Criminal disposal In some cases, a body is disposed of in such a way as to prevent, hinder, or delay discovery of the body, to prevent identification of the body, or to prevent autopsy. In such cases, the deceased is considered a missing person as long as a body is not identified, unless death is so likely that the person is declared legally dead. This often occurs as part of a murder or voluntary manslaughter. In other cases, an
