Why grow hair and nails after death?

Pathologist tells about inertial processes in the human body and organ transplantation.

The growth of hair and nails continues after death, in the first place, because those conventionally called skin appendages do not have such a high degree of organization, which is inherent in other organs. And after biological death, they continue to operate in standalone mode. We can say that the metabolism continues to operate by inertia. These processes are going on and they do not affect vital organs, because in the first die brain and the heart, the kidneys are disabled, the liver, but these fabrics and easy arranged bodies continue to function.

The duration of these processes depends on storage conditions of the body. If the body is in cool conditions, it can last a day or two. And if the body is kept in warm conditions, then pretty quickly begin the processes of decay, and after a few hours of the growth of these tissues is stopped. Generally, the hair can grow for a long time, even a few days after the death, but then the process is still slow-fades. In the animal organism similar changes occur after death, so they too can find the elongation of wool or claws, although some of the processes they are generally faster than a human.

Notice is started when, for example, after the death of a man found him unshaven, appeared suddenly bristles regrown nails - this could be addressed. This could throw in the eye when did the exhumation of the corpse. But these situations are rare, as the decaying process of growth is still going on for long. Then they stopped due to the fact that there is no blood flow, no oxygen supply. But first die vital organs and the tissues while still continue to function.

These processes in antiquity must have been some kind of mystical explanations related to the cult things, but of course, when science began to explain the processes of growth of hair and nails after death, all sorts of mystical and paranormal explanations stepped aside. There really is not anything mystical: the cells remain alive, although the body is dead, but they still continue to exist independently. Different parts of the body die in different ways: the brain, for example, ten minutes is sufficient without oxygen, and the cells begin to die. Other tissues, such as the heart, there may be almost no oxygen hour, and during this time can be taken for heart transplantation. A hair and nails arranged so primitive that can exist independently much longer time, but then it stops.

It is necessary to emphasize another important and interesting point. If all the bodies died out at the same time, if some organs or tissues has not continued to function for some time after death, it would have been impossible organ transplantation. In fact, after the death can take to transplant a liver, a kidney, is now learned how to transplant and lungs, and the heart - all thanks to the fact that the process of the withering away of tissue stretched in time. First, consciousness is turned off, then the vital organs, but they still retain their viability, so they can be transplanted. Otherwise, no transplantation as a field of medicine would not exist, and transplant organs would have been impossible.
