In a person's life, death is something that no one can avoid. When everyone reaches this time, life will end. So have you ever wondered what happens when a person dies, and what unexpected things happen when people die?
When a person dies, the body gradually cools at a rate of 8 degrees Celsius per second until the body temperature drops to the same level as the room temperature. After a while, the person's cells will begin to die from lack of oxygen, then the lungs will lose function and the heart will stop beating. Surprisingly, however, lack of oxygen does not cause human organs to die immediately, they can "live" for a few more minutes. Within these few minutes, some chemical reactions are generated, which in turn produces some carbon dioxide, causing the PH value inside the cell to decrease. Various enzymes in the cell then begin to digest the cell membrane and prompt the cell to be broken down and liquefied. These enzymes then slowly penetrate the cells and begin to break down the cells around them. Isn't it a little scary to sound, human cells have begun to carry out the phenomenon of "big fish eating small fish".
Interestingly, however, muscles begin to become loose after a person dies. If a person has not gone to the toilet before death, it is likely that feces or urine will be excreted at this time.
Then the blood of the human body will flow out of the ruptured blood vessels and flow directly in the human body, and when the person dies, it is basically lying down, so at this time the blood of the whole body will sink to the bottom due to gravity, which is the reason why the face and the body gradually lose blood color and turn white after death.
Another strange thing is that 2-6 hours after death, the phenomenon of corpse stiffness begins to appear. When we are alive, the body can control its own muscle contraction, but with death, all the cells of the human body run out of the last energy, and the protein filament will make the human muscle stop contracting, which is why the body becomes very stiff after death. This stiffness lasts for about 3 days.
Within a few days of death, the body will begin to decay. Bacteria in the gastrointestinal tract begin to break down the body's cells and tissues. The human body begins to liquefy, producing very unpleasant gases, mostly made up of substances such as methane and sulfur hydride. And these gases will make the body's stomach swell, resulting in more and more gas pressure in the abdominal cavity, eventually leading to a variety of fluids in the blood vessels and cells overflowing. If the air pressure is too large at this time, the person's abdomen will explode, and I believe that it will be a nightmare that everyone does not want to see.
When the corpse odor begins, it attracts stomach flies that lay eggs on the rotting corpse, and they can grow into maggots in a day. These maggots eat human flesh and blood and attract large numbers of beetles and other bugs. 20 to 50 days after death, there will be a process called butyric acid fermentation, the rotten flesh will slowly fall off, the human body will be dried, and the body parts that fit the ground will begin to mold. After a dozen or so years, the human body is completely decomposed. After being eaten by some insects and animals, only a skeleton remained in the human body. It really looks like a goosebumps-inducing thing.
Happily, however, most of the bodies can now be disposed of quickly after death, so there is no need to worry about the above phenomenon. The above phenomenon is based on a series of changes produced by the untreated body after death, the human body itself occurs and integrates into nature and nature.
Death may seem like a scary thing, but it can also be a fascinating thing. It has its own unique charm that makes people awe and curiosity about it at the same time.
