When the person's heart stops beating that is called clinical death. Then, when the person can no longer be revived, it is called biological death. How is biological death determined? The breathing of the person must have stopped, as well as the heartbeat. The eyelids may be half open, and the pupils fixed. The person must not be able to be revived. If the cause of death is unknown, an autopsy sometimes occurs. This just allows the cause of death to be determined, and any complications that were unknown involving the death.

After biological death, there are several processes that the body undergoes. The first is the death chill. This occurs right after the heart stops beating. The whole body grows cold, but not any cooler than room temperature. Next is rigor mortis. Rigor Mortis is when blood solidifies in the veins and the whole body becomes stiff. This happens two to six hours after death. At this time some cells still remain alive inside the body, and bacteria begin to break down the body. The color of the body will first begin to change and will go from green to purple, and eventually black. The body will also start to smell and bloat. The bloating is caused by the gas building up inside of the body. This expansion will also cause the eyes to fall out of the sockets and the tongue to fall out of the mouth. After a week, even the slightest touch will cause the skin to fall off because it is so blistered. Finally, after a month of decay, the organs will turn into liquid and the hair and nails will fall off the body. The body bursts open and disintegrates back into the earth. http://metro.co.uk/2015/09/28/putrefying-bloating-and-blistering-this-is-what-happens-to-your-body-after-you-die-5411303/
