Goff explains, “[T]he blood begins to settle, by gravity, to the lowest portions of the body,” causing the skin to become discolored. This process may begin after about an hour following death and can continue to develop until the 9–12 hour mark postmortem.
Livor Mortis (Lividity) is the settling of blood in body due to gravity. Livor Mortis starts to develop 2-4 hours after death, becomes non-fixed or blanchable up to 8-12 hours after death and fixed or non-blanchable after 8-12 hours from the time of death.
Initially the color is red but it later becomes purple as oxygen dissociates from the hemoglobin, changing it to purple-colored deoxyhemoglobin. This color change can be variable depending on the circumstances of death and the environment.
Circulation of blood is a continuous process carried out by the pumping action of the heart in a living individual. However, once the person dies, the circulation comes to a halt, and the blood starts moving towards the dependant regions of the body due to gravity.
There's even a circadian rhythm of death, so that in the general population people tend on average to be most likely to die in the morning hours. Sometime around 11 am is the average time,” says Saper.
In time, the heart stops and they stop breathing. Within a few minutes, their brain stops functioning entirely and their skin starts to cool. At this point, they have died.
For approximately the first 3 hours after death the body will be flaccid (soft) and warm. After about 3-8 hours is starts to stiffen, and from approximately 8-36 hours it will be stiff and cold. The body becomes stiff because of a range of chemical changes in the muscle fibres after death.
Next the funeral director makes a small incision near the clavicle, to access the jugular vein and carotid artery. He inserts forceps into the jugular vein to allow blood to drain out, while at the same time injecting embalming solution into the carotid artery via a small tube connected to the embalming machine.
The brain and nerve cells require a constant supply of oxygen and will die within a few minutes, once you stop breathing. The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day.
What happens to the blood and other fluid removed from the body? It is flushed down the drain! Yes, it enters the sewage system and is treated by the wastewater treatment system in whatever town you are in.
One of the wildest innovations is “living funerals.” You can attend a dry run of your own funeral, complete with casket, mourners, funeral procession, etc. You can witness the lavish proceedings without having an “out-of-body” experience, just an “out-of-disposable-income” experience.
Preserving the Deceased's Remains
To prevent rapid decay, funeral homes drain out the blood and other fluids since they facilitate faster decomposition. They then replace it with anti-decay chemicals. Having the dead body preserved in this way may serve various purposes.
Over time, coffins underground will decompose and eventually collapse. Covering the face before closing the casket adds an extra layer of protection and dignity for the deceased's face and can act as a symbolic final goodbye.
Burials may be placed in a number of different positions. Bodies with the arms crossed date back to ancient cultures such as Chaldea in the 10th century BC, where the "X" symbolized their sky god.
Visual or auditory hallucinations are often part of the dying experience. The appearance of family members or loved ones who have died is common. These visions are considered normal. The dying may turn their focus to “another world” and talk to people or see things that others do not see.
What's really returned to you is the person's skeleton. Once you burn off all the water, soft tissue, organs, skin, hair, cremation container/casket, etc., what you're left with is bone. When complete, the bones are allowed to cool to a temperature that they can be handled and are placed into a processing machine.
A study carried out by researchers at Australia's first 'body farm' also found that corpses can move during the decay process. And it's more than just a twitch. They found that movement occurred in all limbs after death, including in the advanced decomposition stages.
Gasping is also referred to as agonal respiration and the name is appropriate because the gasping respirations appear uncomfortable, causing concern that the patient is dyspnoeic and in agony.
“First hunger and then thirst are lost. Speech is lost next, followed by vision. The last senses to go are usually hearing and touch.”
Research suggests that even as your body transitions into unconsciousness, it's possible that you'll still be able to feel comforting touches from your loved ones and hear them speaking. Touch and hearing are the last senses to go when we die.
The deadliest month in the U.S. is the one that heralds the New Year: January. An average of 251,699 people in the U.S. died in January every year between 2010 and 2020, according to a Live Science analysis of the Centers for Disease Control and Prevention (CDC) Wonder database, which tracks how and when people die.
The Deadliest Day of the Year
But it's also the most dangerous day of the year. According to the Pew Research Center, “45,000 people visit U.S. hospital emergency rooms for treatment of injuries on July 4 and 5 – nearly 91,000 in total, by far the highest daily numbers in the entire year.”
Occasionally a funeral director or family liaison officer will advise a family against viewing the body because of bodily injuries or because of decomposition.
