<unk>  in a dead body Timeline of postmortem changes, including<unk> . Depiction of a body after suicide hanging.<unk>  is fixed in the legs and distal upper extremities because these were the dependent parts.<unk>  (Latin:<unk>  – "bluish color, bruise", mortis – "of death"), postmortem lividity (Latin: postmortem – "after death", lividity – "black and blue"), hypostasis (Greek: ὑπό, hypo, meaning "under, beneath"; στάσις, stasis, meaning "a standing") or suggillation, is the fourth stage of death and one of the signs of death. 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. The blood travels faster in warmer conditions and slower in colder conditions.<unk>  starts in 20–30 minutes, but is usually not observable by the human eye until two hours after death. The size of the patches increases in the next three to six hours, with maximum lividity occurring between eight and twelve hours after death. The blood pools into the interstitial tissues of the body. The intensity of the color depends upon the amount of reduced haemoglobin in the blood. The discoloration does not occur in the areas of the body that are in contact with the ground or another object, in which capillaries are compressed.
