It is a settling of the blood in the lower, or dependent, portion of the body postmortem, causing a purplish red discoloration of the skin. When the heart stops functioning and is no longer agitating the blood, heavy red blood cells sink through the serum by action of gravity.
A cadaver, often known as a corpse, is a dead human body. Cadavers are used by medical students , physicians and other scientists to study anatomy , identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being.
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).
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.
The cell body is the part with the nucleus in it. The body of a dead person is also called a corpse or cadaver. The dead bodies of vertebrate animals and insects are sometimes called carcasses. The human body has a head, neck, torso, two arms, two legs and the genitals of the groin, which differ between males and females.
The body is disinfected and insects such as maggots and flies are removed. [1] The body is then washed with water and germicidal soap. This movement of the body parts also helps to relieve rigor mortis, [2] and particular attention is given by the embalmer to parts of the body that are most visible during a viewing: the facial area and hands.
A key principle in the dissection of human cadavers (sometimes called androtomy) is the prevention of human disease to the dissector.Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique [2] and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses.

Skeletonization is the state of a dead organism after undergoing decomposition. [1] Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed.
