HE american chemical society created an extremely detailed video that reveals minute by minute what happens to the human body after the death.
What happens to the human body when it dies?
Initially, the heart stop beating like that blood circulation is interrupted over the whole body. Blood clots form (clots) and blood it gets thicker. At the same time, body temperature also falls the muscles they become less flexible (dead stiffness).
The next cessation of breathing and the inability to supply cells with oxygen causes them to gradually… die. are released enzymes that open the development bacteria and fungi and thus begins the decomposition process.
The body must be temporarily preserved – until the funeral takes place – preservative substances such as formaldehyde and the glutaraldehyde.
Minute by minute the process
The unpleasant odors given off by the corpse are mainly due to two chemical substances, putrescine and cadaverine .
According to the experts, the analytical process of the mortuary rigidity of the body comprises the following stages:
-
Human cells open wide
The process in which the human body breaks down begins just a few minutes after death. When the heart stops beating, the person experiences the so-called “cold of death”, when the body temperature drops around 1.5 degrees Celsius per hour to reach room temperature. Almost immediately, the blood becomes more acidic as carbon dioxide builds up.
This process causes the cells to “open” wide, essentially emptying the tissues of enzymes, which begin to digest the tissues from the inside.
-
The body takes on a whitish color
Gravity makes its presence felt especially in the human body, from the first moments after death. While the rest of the body turns whitish, the heavier red blood cells move towards the parts of the body that are closer to the ground. This is because blood circulation has stopped. The result of this movement is the purple spots on the parts of the body that touch the ground (for example, on the back if the corpse is lying on its back).
In fact, these signs help the medical examiner determine it. time of death.
-
calcium shrinks them muscle
It’s about the calls rigor mortis, in which a corpse becomes rigid and difficult to move. The stiffness usually begins within three to four hours after death, it peaks at 12 hours and dissipates after 48 hours.
Why is this happening; In the membranes of muscle cells there are pumps that regulate calcium. When these pumps stop working after death, calcium floods the cells, causing the muscles to contract and stiffen, hence the deadly rigidity.
-
The organs are assimilated.
HE septicemia it is the process that follows mortuary rigidity. This phase can be delayed, in the case of embalming, but eventually the body will succumb at some point. And the cause is the same enzymes present in the pancreas, which will force the organ to start digesting. Germs will “attack” these enzymes en masse, giving the body a greenish colorStarting since belly.
As experts report, “Those who benefit from this process are approximately 100 trillion bacteria that they have spent their lives harmoniously within the human bowels.” But as these bacteria cause the human body to decompose, they release putrescine and cadaverine, the compounds that give a dead person their odor.
-
“wax” coating
After dialing, continue the decay process which is quite fast actually turns the body into a skeleton. However, in this process there are several external factors that play an important role. If a body comes into contact with cold or watery soilcan be developed adipokeros or cadaveric wax, an oily and waxy material resulting from the alteration of the lipids during the decomposition of the carcass.
HE adipose acts as a natural preservative for internal organs, a fact that may mislead investigators as to exact time of death.
A typical, albeit rare, example is the case of the corpse of a 300-year-old man found a few years ago in Switzerland.
