Why does a person s body decay? When a person dies, does the body decay?

Corruption: The rate at which a corpse decomposes is greatly affected by the temperature of the environment, the cause of death, and the individual's constitution. In the human body, because the ileocecal part is easy to accumulate feces, the decay occurs earlier after death, and more hydrogen sulfide is produced, so the corpse green first appears in the right lower abdomen.

Corpse green usually begins to appear at the end of the first day and night, and then gradually expands, spreading to the entire abdomen and then to the whole body. Generally speaking, corpses decompose most rapidly in summer, and corpse green begins to appear in the right lower abdomen, which has been more than 2 4 hours after death; If the corpse is a giant, it has been dead for more than 3 days; About 15 days after death, the soft tissues of the whole body decay, chyme, collapse, and digest. In winter, corpses decompose more slowly, and they don't even decay in snow and ice.

When there are factors that favor the development and reproduction of bacteria, the corpse decays quickly; Otherwise slow down or stop. At a temperature of 2 5 to 35 degrees Celsius, with proper humidity and air circulation, decay fast. Experiments have proven:

The ratio of time required for a corpse to decompose in the air, in water and in the ground is 1:2:8.

In addition, the speed of decay of corpses is also related to the physical state, such as young children's corpses have more moisture, suffocation and sudden death of corpses due to blood mobility, sepsis deaths due to the presence of a large number of bacteria, decay faster.

Most of the body of ordinary people is water, when people die, if the water of the body is removed, it will not be easy to rot, in the internal organs of people, the decay of internal organs is the easiest, if you do not eat or drink, it is easy to dry up the internal organs. But most people can't achieve it, people eat grains, and the toxins in the body are easy to rot.

After death, the body will completely decompose after a month.

Within 1 hour of death, the body will begin to cool down and become stiff. 30 hours after death, due to the presence of a large number of bacteria in the body, it will begin to decompose the internal organs, and the decay will produce a large amount of gas, which will fill the abdomen.

Within a week or so, the body's tissues are consumed by bacteria and maggots, and the body begins to leak white bones, and then it only takes a month or so for the body to completely decay.

After the decaying gases entered the tissues, the trunk and limbs of the corpse were visibly swollen. The constant production of putrefactive gases increases the pressure inside the corpse. In the process of decay, the ** tissue of the body is the most lacking, and Lu Zhen finally ruptures, and the decaying cavity gas begins to come to the outside of the corpse.

Debridement: If the flesh on the human body is decomposed, it usually means that the local tissue is necrotic, and you need to go to the hospital to find a doctor to remove all the tissues in the decayed area; Disinfection: When all the decaying tissue in the wound is removed, a more obvious wound may be formed, in order to avoid infection at the wound site, the wound can be rinsed with normal saline, and then further disinfected with iodine.

The whole body decay should be cleaned with double volt coarse oxygen water, the wound surface should be disinfected with iodine, and finally applied with sterile gauze.

Microorganisms decompose.

In general, the corpse hardens within 30 minutes to 2 hours after death, completely stiffens after 9 to 12 hours, softens after 30 hours, and returns to its original state after 70 hours. However, if it is in soil or water, or in the case of low temperature and dryness, it will be delayed, and it will be accelerated under high temperature and humidity conditions.

Coldness of the face and limbs, corpse spots, and stiffness began to appear, and the elapsed time after death was 1 2 hours. The corpse spots are distributed in patches, and the zombies appear for the most part, and the time of death passes for 3 to 4 hours. The corpse spots fused into large patches, the corpse appeared all over the body, the cornea was slightly cloudy, the lips began to wrinkle, and the pupils still reacted with mydriatic and mydriatic drops, and the elapsed time after death was 5 to 6 hours.

Zombies are highly developed, acupressure corpse spots can completely fade, the cornea is highly opaque, and the ocular conjunctiva begins to autolyze about 12 hours after death. The corpse spots can be completely depressed, parchment paper-like spots form, the cornea is highly opabid, scleral dark spots appear, the oral mucosa and ocular conjunctiva are autolyzed, and about 24 hours have elapsed after death.

The timing of the appearance of the above-mentioned corpse phenomena is based on the spring and autumn seasons, which accelerates in summer and slows down in winter.

Deputative abdominal distention, which begins at 8 10 hours after death in spring and autumn, 4 5 hours after death in summer, and 48 72 hours after death in winter. Putrefactive green spots begin to appear about 24 hours after death in spring and autumn, about 12 hours after death in summer, and 72 120 hours after death in winter.

The network of decaying vessels begins to appear in spring and autumn at 48 to 72 hours after death, in summer at 1 2 days after death, and in winter at about 7 days after death. Hair is prone to loss and putrefactive blisters, which appear in spring and autumn at 3 to 5 days after death, in summer at 1 to 2 days after death, and generally do not appear in winter.

The view of the corrupt giants begins to appear in spring and autumn at 3 7 days after death, in summer at 2 3 days after death, and in winter at 15 30 days after death. In the middle of summer, the soft tissues of the corpse liquefy and disappear, and only the bones remain, which takes about a month, and in the case of fly destruction, the time will be shortened. If the corpse is in the water, there are still some corpse phenomena for speculation that the hands and feet are soft and swollen at the time of death, showing a white wrinkled phenomenon, and if it appears in the palms and soles of the feet, the time of death is about 4 hours; If it appears on the back of the hand or foot, the time of death is about 48 hours.

The phenomenon of hands and feet falling off and becoming glove-like, if it appears on the corpse in summer, the time of death is about a week; Winter is around January; In spring and autumn, it is about 2 weeks. The view of the corrupt giant, which appears in the spring and autumn seasons at 7 10 days after death, in the summer at 4 5 days, and in the winter months in the month. It needs to be emphasized again that the occurrence and development of the cadaveric phenomenon is constrained by various conditions.

Why do people decay when they die, and what prevents the body from decaying while they are alive?

When a person dies, the body decays, so why doesn't the human body decay while alive?

Man is an animal, the body is made up of chemicals, and when a person dies, the cells are dead, and the body decays.

After death, the blood stops flowing, and there is no blood, so decay occurs.

Due to the decomposition action of bacteria.

First of all, it affects the appetite of the person.

The putrescine and cadaverine produced are highly toxic chemicals.

In the wars that took place in Central Asia in the Middle Ages, the defenders placed dead cattle in the water sources and wells along the way, causing the attackers' troops to become plagued.

It is said that Huo Qubing died in the final blow to the Xiongnu that year due to drinking contaminated water.

After the protein is broken down, cadaverine is produced, which is toxic.

The smelly stuff is cadaverine (1,5-pentanediamine) and putrescine (butanediamine).

Not necessarily, the appearance of decay indicates that there is a problem with the muscles of the body, such as the wound infection and necrosis, if it is left to rot all the time, the serious one will be amputated, and the more serious one may die ......

When a person is still alive, there is decay in some parts of the body, which has nothing to do with whether he dies or not, and some diseases will lead to such a phenomenon, for example, when the diabetic is serious, there will be ulcers on the body, and it is not easy to cure.

Not necessarily. If every pound of meat is not properly handled, he will also rot. If the wound is not treated for a long time, the wound of the amputation will turn black. You'd better go to the hospital to have the wound treated. See what the doctor says.

All animals will rot.
