How many years does it take for a bone to decay?

It depends on the temperature, but if the temperature is high, it will rot within a month, and it will turn into white bones after three months.

Generally, it takes 10 to 15 years. It can be said that the bones are not visible, but under normal circumstances, they will rot after three to five years.

Generally speaking, it will rot after about 20 years, but there are special cases where it can not rot until after 30 years.

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.

In a week or so, various tissues in the human body will be covered by bacteria and maggots.

With little left, the body begins to leak white bones, and then it only takes a month at most for the corpse to completely decompose.

If there is a lot of moisture in the buried place, then it will accelerate the decay of the bones, and if it is a relatively dry place, the bones will continue to rot for many years, and some will not rot after 20 or 30 years. When you open the cemetery, it will still be basically the same as when it was first buried. So how long it takes for the bones to rot depends on what kind of geographical environment they are in.

If the burial chamber is well enclosed and there is very little air inside, it is possible to keep it forever.

1. In a cold and dry place, the degree of decay of the corpse will be slower.

2. In general, the corpse buried in the soil will begin to decompose after 8-9 days, and will decompose into white bones in more than 2 months.

3. It depends on what kind of environment it is in, a dry and sealed environment, which can be stored for hundreds or thousands of years, a humid environment, and an environment with insects, it will be very fast.

4. This is determined by many factors, the degree of airtightness of the tomb, the permeability of the soil, the existence of groundwater, and whether the corpse has been treated before burial all determine the speed of decay.

Expand your information; 1. The body is self-declining and bacteria are breeding

1. After 30 minutes to 2 hours after the loss of function of the human body, it will begin to harden, and the phenomenon of corpse coldness (the whole body is cold) and corpse stiffness will appear.

It will start from the face and extend downwards, and the whole body will be stiff and noticeable in 9-12 hours. Blood in the human body will be deposited in the lower parts of the body in the direction of gravity due to the cessation of circulation, resulting in corpse spots.

2. If the newly produced corpse spot is acupressured, the position will change, but if it has been more than 12 hours after death, the corpse spot will not change its position. Because by this time the blood has completely coagulated.

Second, the corpse swells and decomposes

1. After 30 hours after death, the corpse will begin to soften, and the abdomen, as the part of the body with the most bacteria and fat, will be the first to soften and decay.

2. The putrefactive bacteria in the stomach and intestines produce a lot of gases and hemoglobin in the blood.

Sulfides will begin to form, corpses can be seen to swell significantly, and the skin of the body will begin to turn orange or yellow, and these putrefactive gases will begin to attract flies.

Eggs are eaten by maggots or other organisms that eat putrefaction. And maggots.

It usually enters the body from the head, eyes, nostrils, and mouth to eat.

3. The outflow of corpse water and the entry into the biological removal procedure:

1. About 5-6 days after death, the corpse has its metabolites accumulated inside after being eaten by maggots, such as: nitrogen, ** corpse bubbles gradually begin to appear on the surface, or black corpse water directly oozes.

2. At this time, ** is separated from the muscles, and if the force is greater, the whole skin can be faded, and the hair will also fall off.

Fourth, it is dried and turned into dry bones.

1. One week after death, the corpse will enter the final biological removal stage, and the length of the event in this stage will change according to the climate, humidity and maggot infestation where the corpse is located.

2. Generally speaking, the summer is hot and humid.

It will accelerate the decay of the corpse, and only white bones will be left in about 1 month; About a month in spring and autumn; Winter is longer, about 2 months.

Causes of corpse decomposition:

When the corpse is not yet a corpse, there are many bacterial groups inside the self-service, and the human body removes the metabolites of the bacteria through metabolism and provides food for the bacteria through eating.

When they die, they no longer eat, but the metabolism of bacteria continues, and because they can't metabolize the metabolites of bacteria, they will rot.

The process of decomposing the corpse:

The heart stops beating, no longer delivers oxygen to the body's cells and tissues, and life ends. Usually within 3 to 8 minutes, brain cells die first, and bones and ** cells can continue to survive for a few days. Blood will flow out of the capillaries and collect in the lower parts of the body, so some parts of the body are pale, while others are darker and are called corpse spots.

About 3 hours after death, there is a phenomenon of rigor mortis, that is, the muscles become hard. About 12 hours after death, the body will become cold. Within 24 hours (depending on the fat content of the body and the external temperature), all heat inside the corpse will be lost.

This process of losing heat is called corpse cold. About 36 hours after death, the tissues will excrete green substances and release methane, H2S, and other gases. The corpse's lungs will drain fluid through the mouth and nose.

Generally speaking, after death, some microorganisms and bacteria in the corpse still exist, and the gas produced by their metabolism will be discharged by the human body before death, but after death, these gases will accumulate in the corpse, and the whole corpse will be flatulent, especially the stomach will bulge. When the flatulence reaches a certain stage, after the corpse is broken, the liquid in the corpse will flow out and spread to the surface of the corpse, and the microorganisms in the body will spread to the surface of the corpse with the liquid, and the external manifestation is that maggots crawl all over the surface of the corpse, and gradually decompose the corpse into a puddle of liquid, which is dried or infiltrated into the soil...

27 The corpse will start to stink in two or three days, and if there is a lot of humidity in your area, it will start to stink in two days, so it is best to go to the funeral home and freeze it in a freezer for preservation.
