Decomposition begins several minutes after death with a process called autolysis, or self-digestion. Soon after the heart stops beating, cells become deprived of oxygen, and their acidity increases as the toxic by-products of chemical reactions begin to accumulate inside them.

The great bulk of the fossil record is dominated by fossils of animals with shells and microscopic remains of plants and animals, and these remains are widespread in sedimentary rocks. It is these fossils that are studied by most paleontologists.

Living organisms require these nutrients to create cells, tissues and to provide energy for life processes. When a plant or animal dies, nutrients would remain forever locked in the dead tissues if it weren’t for decomposers. The decomposers complete the cycle by returning essential molecules to the plant producers.

Summary: For plants and animals, and for humans as well, it is important that cells both can develop and die under controlled forms. The process where cells die under such forms is called programmed cell death.

Hearing is widely thought to be the last sense to go in the dying process. Now UBC researchers have evidence that some people may still be able to hear while in an unresponsive state at the end of their life.

In most cases, when a patient is receiving the care and support of hospice, they will not experience pain during the dying process. Instead, their body will naturally begin to shut down. They will begin to have a decreased desire to eat and drink and will start to sleep more.

The Catholic conception of the afterlife teaches that after the body dies, the soul is judged, the righteous and free of sin enter Heaven. However, those who die in unrepented mortal sin go to hell.

But there is no certainty as to when or how it will happen. A conscious dying person can know if they are on the verge of dying. Some feel immense pain for hours before dying, while others die in seconds. This awareness of approaching death is most pronounced in people with terminal conditions such as cancer.

According to the 9th century Zoroastrian text Dadestan-i Denig (“Religious Decisions”), a soul is judged three days after death. Depending on the soul’s balance of good and bad deeds, it goes to heaven, hell, or hamistagan, a neutral place. In its appropriate place, the soul awaits Judgment Day.

In scientific literature such experiences have been referred to as death-related sensory experiences (DRSE). Dying patients have reported to staff working in hospices they have experienced comforting visions. Modern scientists consider deathbed phenomena and visions to be hallucinations.

A life review is a phenomenon widely reported as occurring during near-death experiences, in which a person rapidly sees much or the totality of their life history. It is often referred to by people having experienced this phenomenon as having their life “flash before their eyes”.

As death nears, the person’s metabolism slows contributing to fatigue and an increased need for sleep. The increase in sleep and loss of appetite seem to go hand in hand. A decrease in eating and drinking creates dehydration which may contribute to these symptoms.

Key facts. When someone is dying, their heartbeat and blood circulation slow down. The brain and organs receive less oxygen than they need and so work less well. In the days before death, people often begin to lose control of their breathing.

Instead of peacefully floating off, the dying person may cry out and try to get out of bed. Their muscles might twitch or spasm. The body can appear tormented. There are physical causes for terminal agitation like urine retention, shortness of breath, pain and metabolic abnormalities.

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.

Breathing may become irregular with periods of no breathing or apnea lasting 20-30 seconds. Your loved one may seem to be working hard to breathe — even making a moaning sound. The moaning sound is just the sound of air passing over very relaxed vocal cords. This indicates that the dying process is coming to an end.

So, what does it feel like to die? As these studies record, death by cardiac arrest seems to feel either like nothing, or something pleasant and perhaps slightly mystical. The moments before death were not felt to be painful. We don’t know if this would extend to other causes of death, but still, it is reassuring.

• Decreasing appetite. Share on Pinterest A decreased appetite may be a sign that death is near.
• Sleeping more.
• Becoming less social.

• Dropping body temperature.
• Experiencing confusion.

Saying, “I forgive you” can clear the way for a deeper sharing of the remaining time. It can also give you a sense of peace following the person’s death. Due to defensiveness, a lack of understanding, or some other reason, the person may not be ready to acknowledge the deep hurt in your relationship.

When a person is just hours from death, you will notice changes in their breathing: The rate changes from a normal rate and rhythm to a new pattern of several rapid breaths followed by a period of no breathing (apnea). This is known as Cheyne-Stokes breathing—named for the person who first described it.

In the last hours before dying a person may become very alert or active. This may be followed by a time of being unresponsive. You may see blotchiness and feel cooling of the arms and legs. Their eyes will often be open and not blinking.

Hands, feet and legs may feel cool or cold to the touch. Blood pressure gradually goes down and heart rate gets faster but weaker and eventually slows down. Fingers, earlobes, lips and nail beds may look bluish or light gray.

The brain is the first organ to begin to break down, and other organs follow suit. Living bacteria in the body, particularly in the bowels, play a major role in this decomposition process, or putrefaction. This decay produces a very potent odor. “Even within a half hour, you can smell death in the room,” he says.

Death is not like falling asleep. It is something very different. If you are not sure about death, you should ask questions about it. It’s hard for people to talk about death and ask questions about it, but getting answers will make you feel better and have less stress.

The human brain can continue functioning for more than 10 minutes after the body has died, scientists have discovered. Intensive care doctors reported observing the same kind of brain waves in a patient whose pulse had stopped and whose pupils were unreactive as occurs during deep sleep in healthy people.
