Lividity

Lividity, also known as postmortem Lividity or hypostasis, is the pooling of blood in the lowest parts of a body after death. It is a visible sign that indicates the cessation of circulation. This discoloration typically appears as a purplish or reddish-blue hue, often noticeable on the skin. The process is influenced by gravity and blood vessel integrity. It can be used in forensic science to estimate the time of death, and to determine the body's position after death, and to identify if the body has been moved.
