Bone and skin cells can stay alive for several days. It takes around 12 hours for a human body to be cool to the touch and 24 hours to cool to the core. Rigor mortis commences after three hours and lasts until 36 hours after death. Forensic scientists use clues such as these for estimating the time of death.

The fastest transformation from corpse to skeleton at the Body Farm happened in just 12 days. But if a person is buried two feet underground, total skeletonization can take six months, Jantz says. A body six feet under takes more than two years. A body will also skeletonize faster if it is buried in acidic ground.

It can take between eight and twelve years for an unembalmed body buried six feet down, to decompose to a skeleton. This can vary – or take longer– depending on the climate, moisture in the soil and the kind of coffin they were buried in.

The average time for an adult cremation is 90 minutes at a temperature of between 800 and 1000 degree Celsius. On average from insertion to final cooling the cremation process may take up to four hours.

The body of a brain-dead person is usually not supported for very long, Greene-Chandos said. Doctors sometimes provide support (in the form of a ventilator, hormones, fluids, etc.) for several days if the organs will be used for donation, or if the family needs more time to say good-bye, Greene-Chandos said.

This process begins around 2 to 6 hours after death and typically lasts for 24 to 84 hours, depending on environmental temperature and the state of the body. A lower temperature will usually prolong the duration. After this time the muscles then begin to relax.

When buried six feet down, without a coffin, in ordinary soil, an unembalmed adult normally takes eight to twelve years to decompose to a skeleton. However if placed in a coffin the body can take many years longer, depending on type of wood used.

All cells need oxygen to survive, but different cells die at varying rates. Brain cells, for example, die within minutes; while, skin cells can survive over 24 hours after death. Have you ever noticed that a dead person's skin looks ashen?

What happens to your body after you die? ... The first, clinical death, lasts for four to six minutes from the moment a person stops breathing and the heart stops pumping blood. During this stage, organs remain alive and there may be enough oxygen in the brain that no permanent damage occurs.

24-72 hours after death — the internal organs decompose. ... 1 month after death — the body starts to liquify.

Originally Answered: How long does it take for a dead body to start smelling? It depends on many factors such as temperature,humidity, age, and gender. On average, my best estimated average would be 24-36 hours although it could be as few as 8 to 12.

After the heart stops beating, the body immediately starts turning cold. This phase is known as algor mortis, or the death chill. Each hour, the body temperature falls about 1.5 degrees Fahrenheit (0.83 degrees Celsius) until it reaches room temperature.

The rate at which this cooling occurs depends on the temperature differential between the body and the environment (elevated body temperatures and cool ambient temperatures will increase this rate), but as a general rule, the body cools at a rate of about 1.5°F (0.8°C) per hour during the first 12 hours.

When buried six feet down, without a coffin, in ordinary soil, an unembalmed adult normally takes eight to twelve years to decompose to a skeleton. However if placed in a coffin the body can take many years longer, depending on type of wood used. For example a solid oak coffin will highly slow down the process.

24-72 hours after death — the internal organs decompose. 3-5 days after death — the body starts to bloat and blood-containing foam leaks from the mouth and nose. 8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas.

Rigor mortis, the stiffening of the joints, typically begins within 10 minutes to three hours after death and can last as long as 72 hours. Again, the temperature will affect this process. Ideally, the remains will be properly handled before the onset of rigor mortis.
