A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
Dyes. Active dyes are used to restore the body's natural colouration and counterstain against conditions such as jaundice as well as to indicate distribution of arterial fluid. Inactive dyes are used by the manufacturer of the arterial fluid to give a pleasant color to the fluid in the bottle but do nothing for the appearance of the embalmed body.
Pallor mortis occurs almost immediately, generally within 15–25 minutes, after death. Paleness develops so rapidly after death that it has little to no use in determining the time of death, aside from saying that it either happened less than 30 minutes ago or more, which could help if the body were found very soon after death.
The health risks of dead bodies are dangers related to the improper preparation and disposal of cadavers. While normal circumstances allow cadavers to be quickly embalmed , cremated , or buried ; natural and man-made disasters can quickly overwhelm and/or interrupt the established protocols for dealing with the dead.
The disposal of human corpses, also called final disposition, is the practice and process of dealing with the remains of a deceased human being.Disposal methods may need to account for the fact that soft tissue will decompose relatively rapidly, while the skeleton will remain intact for thousands of years under certain conditions.
A dead body holds its position as rigor mortis sets in. If the body is moved after death, but before rigor mortis begins, forensic techniques such as livor mortis can be applied. Rigor mortis is known as transient evidence, as the degree to which it affects a body degrades over time.
Cadaveric spasm may affect all muscles in the body, but typically only groups, such as the forearms, or hands. Cadaveric spasm is seen in cases of drowning victims when grass, weeds, roots or other materials are clutched, and provides evidence of life at the time of entry into the water.
Mutilation, by contrast, involves "the removal or irreparable disfigurement, by any means, of some smaller portion of one of those larger sections of a living or dead person. The latter would include castration (removal of the testicles), evisceration (removal of the internal organs), and flaying (removal of the skin)." According to these ...
