What is the difference between rigor and lividity?
After a period of six to eight hours after death, lividity becomes totally fixed. Rigor Mortis is the stiffening of muscles after death. The muscle stiffening (hence the use of the term, stiff) is caused by the loss of adenosine triphosphate (ATP) from the muscle tissue.
What does livor mortis or lividity refer to?
Livor mortis, also known as lividity or hypostasis, is the gravitational pooling of blood to lower dependant areas resulting in a red/purple coloration. Although livor mortis is commonly seen between 2 and 4 h postmortem, its onset may begin in the ‘early’ period, as little as 30 min postmortem.
What can lividity be used to determine?
The term lividity refers to an unnatural color of the skin. Lividity can be a useful reaction in determining the position of a body at the time of death and even whether a body was moved within the first few hours after death. Lividity can also result when blood flow ceases after death.
How long after death does lividity begin?
Lividity usually begins 30 minutes to 4 hours after death and is most pronounced 12 hours after death. Blanching, or a whitish discoloration that results when pressure is applied to the skin, can occur up to 8–12 hours after death. After this time period, however, the blood becomes fixed (or non-blanchable).
What are the 7 stages of dying?
“Death is not the greatest loss in life. The greatest loss is what dies inside us while we live.” However, there are actually seven stages that comprise the grieving process: shock and disbelief, denial, pain, anger, bargaining, depression, and acceptance/hope.
Can a person who is dying hear you?
While the dying person may be unresponsive, there is growing evidence that even in this unconscious state, people are aware of what is going on around them and can hear conversations and words spoken to them, although it may feel to them like they are in a dream state.
What happens as soon as you die?
Decomposition begins several minutes after death with a process called autolysis, or self-digestion. Soon after the heart stops beating, cells become deprived of oxygen, and their acidity increases as the toxic by-products of chemical reactions begin to accumulate inside them.

What causes the lividity of the body after death?
Lividity is the bluish-purple discoloration of skin after death. It is a sign of livor mortis and occurs when blood pools at the lowest point of the body due to gravity and loss of blood circulation.
What causes lividity on the right side of the body?
The blood that was formerly flowing through the body can be drawn to the lowest point in the body by the influence of gravity. For example, if a victim was lying on her right side at the time of death, lividity would be evident on the right side of the face, hip, and on the areas of the right arm and leg that were closest to the ground.
