Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.
- After death, the stomach contains identifiable ingested foods within two hours.
- Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.
- Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.
