What happens to the body within 48 hours of death?

Death means the end of life. In our country, "death" has always been a topic that Chinese people avoid, but with the development of philosophy and modern life science, "death" has gradually receded the veil of mystery, everyone will face death, and no one can remain young and immortal. So, when a person's life is finally over, what does it do?

In order to better face "death", let's understand what happens to human beings within 48 hours of death.

A shocking study in the United States has shown that when a human heart stops beating, the brain continues to function. In other words, the human brain becomes aware of the fact that it is dead. Some people will begin to twitch, their breathing will change from a normal rhythm to a rapid one, and their ears will become cold first.

The blood in the body turns acidic and the throat begins to spasm. When the brain excretes all oxygen, it is considered medically dead, and the person's pupils turn into a substance that looks like glass crystals.

Within an hour after death, the person's ** also began to change color due to the blood clotting throughout the body, the skin muscles were in a state of complete relaxation, and the intestines and bladder began to empty. Without blood pressure, the eyeballs will slowly flatten from the sphere, and the pupils will dilate and then begin to lose their luster. Brain cells also begin to die in batches, and the brain may continue to think, thinking about what to do not die, some experiences before death, and so on.

Within 1 to 4 hours after death, the muscles of the body begin to stiffen, the hair stands on end, and the person's hair and nails become longer due to the atrophy of the muscles and hair follicles, which is also the origin of the longer hair of the corpse in many movie plots.

4 to 6 hours after death, the muscles of the body continue to stiffen, the blood clotting has also reached a certain level, the phenomenon of "zombie" begins to spread, and the color gradually turns black. After 6 hours after death, the muscles of the body will spasm and there will be a persistent anaerobic physiological reaction. Eight hours after death, at this time, the body is basically completely cold, and the temperature is similar to the outside world.

Not ...... thoughIt is possible for men to achieve the last strength in life. 36 to 48 hours after death, the body begins to soften, ** turns white, and the phenomenon of mortis begins to disappear. Corpse spots begin to spread all over the body, and the color of the corpse spots on the body will be different depending on the way of death, and the corpse spots that appear on the body after natural death are generally dark purple-red.

Due to the presence of a large number of bacteria in the body, the protein-rich internal organs in the body begin to decay, and the pancreas begins to digest itself, and the tissues and cells in the body will be eroded by various enzymes until the tissues become soft and liquefied, and the "autolysis" process continues until it slowly disappears. In this whole process, the body will emit oxygen, nitrogen, hydrogen, carbon dioxide, methane, ammonia, hydrogen sulfide and other components with a strong odor due to erosion, which is called "corpse odor".

Life is wonderful and precious, even if it ends up in dust, we still have to cherish every day in this world!

After death, blood no longer circulates and the blood vessels in the brain are insufficient, which can cause discoloration of the eyeballs. At the same time, because the blood supply to the body is insufficient, the blood no longer circulates, resulting in changes in the body, and the temperature of the body will gradually become very cold.

The body organs stop working, the brain waves disappear, corpse spots appear, and the pupils of the eyes will dilate and slowly lose their color.

The organs are starting to stop functioning, and the internal structure of the body is undergoing drastic changes to adapt to the new environment.

Summary. Hello dear, because the body does not immediately lose its vitality after death, and some cells are still alive, because the blood in the body is still flowing, but the speed is getting slower and slower. Then with the extension of time, the human body will gradually enter a state of low activity, and finally the vital signs disappear completely, just after death, the person is actually unconscious, the heart will not beat, and some other life characteristics slow down, but still exist, but after the brain dies, the person has been declared dead, because when the person is alive, it is the human brain, and there is normal consciousness in normal activities.

Why does consciousness exist for 48 hours after death?

Hello dear, because the body does not immediately lose its vitality after death, and some cells are still alive, because the blood in the body is still flowing, but the speed is getting slower and slower. Then with the extension of time, the human body will gradually enter a state of low activity, and finally the vital signs disappear completely, just after death, the person is actually unconscious, the heart will not beat, and some other life characteristics slow down, but still exist, but after the brain dies, the person has been declared dead, because when the person is alive, it is the human brain, and there is normal consciousness in normal activities.

Dear, after a person dies, some cells can survive for 48 hours, but the life and death of a person cannot be reversed, because our body does not depend on whether some cells survive, but on whether the overall brain consciousness still exists, our consciousness disappears, our brain dies, then our body will gradually die.

Dear, a study in the United States showed that when a person's life is just at the end of its life, the heart stops beating, and the human brain knows that it is dead. Studies have shown that the brain does not stop working immediately after death, that is, within a short period of time after death, the person is conscious of knowing that he has died, but the body cannot make any movements, and it feels like being "trapped" in the body.
