After death, a series of complicated changes would occur. From a physiological point of view, death was divided into heart death and brain death. When the heart died, the heart would stop beating, the blood circulation would be interrupted, and the oxygen supply to the organs and tissues of the whole body would stop. Blood pressure would drop, heartbeat and breathing would stop, and the metabolism in the cells would gradually weaken. Brain death was the irreversible loss of brain function, which would affect the functions of various organs in the human body, causing the biochemical reactions in the cells to go out of control. Finally, the cells would die, causing damage to the tissues, organs, and even the entire body until the vital signs disappeared completely. After death, the body would also show various signs of being a corpse. The first was cold corpse. After a person died, as a warm-blooded animal, they would lose body heat. It usually appeared between 1 to 2 hours after death. Lividity mortis, which usually appeared two to four hours after death, was caused by the blood circulation stopping. The blood in the cardiovascular vessels accumulated in the lower part of the body along the blood vessel network, filling the capillaries and small veins in the lower part of the body with blood. The dark red to dark purple-red spots appeared through the skin. The development process was from cloud-like, strip-like, and finally to sheet-like. Lividity mortis could be used to identify the time of death or to determine whether it was hit. Corpse stiffness usually appeared 1 - 3 hours after death, spread to the whole body 4 - 6 hours after death, reached its peak 12 - 16 hours after death, and weakened after 24 hours. If the corpse was not treated, it would eventually rot and turn green. This was caused by the decomposition of microorganisms on organic matter to produce excrement, gas, or the activity of microorganisms. The gas emitted by microorganisms had a foul smell. In addition, different beliefs and ideas had different explanations for the fate of people after death, such as reincarnation, going to heaven or going to hell, but science had not given a more objective and reliable answer. However, in some special situations, such as near-death experiences, some people claimed to have out-of-body experiences, such as being able to see things around them, hear what was happening, etc. However, these phenomena had not been fully explained by science. Some studies believed that it was a reaction of the brain when it was extremely close to death.
