Has it ever occurred to you why cotton wool is usually stuffed in a dead person’s nostrils and ears?
If that question has been lingering in your mind, then the answer is here.
When a person is reported dead, science has it that his/her body starts loosing temperature to the atmosphere such that the body ends up losing all the resistance it had against germs which initiate the process of body decaying.
Because the body now has no resistance to germs, decay will start occurring inside the body of the dead.
Usually, the first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. ie (As soon as blood circulation and respiration stops) and the body has no way of getting oxygen or removing wastes.
Excess carbon dioxide causes an acidic environment in the dead body causing membranes in cells to rupture.
The membranes release enzymes that begin eating the cells from the inside out.
This decomposition will cause gases to start generating and building up due to decay of food which was in the digestive system before death occurred.
This gases (methane, hydrogen sulfide, and carbon dioxide ) will start escaping through all the body openings or any other openings that might have developed at the time of death such like during a fatal injury to different parts of the body.
That is why at times, gargling sound emits from bodies even after hours of death. So before “packing ” of the dead body, the professionals / morgue attendants in Hospital Mortuaries or the funeral parlours, extract many such contents from inside body and stuff with synthetic cotton wool dipped in Chemicals which will kill any germs from coming out of the body.
