After two weeks, the body starts to bloat and change its color to red after the blood present in the body starts to decompose. Once the corpse surpasses the fourth week, you can witness liquefaction in the rest of the remains. The teeth and nails also begin to fall during this time frame.
8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas. Several weeks after death — nails and teeth fall out. 1 month after death — the body starts to liquify.
Two Weeks & Beyond
After two weeks of decomposition, the body will be swollen due to gas formation and display a reddish hue as the blood decomposes. As the body enters the active decay stage, organs, muscles, and skin become liquefied, and the body experiences significant mass loss.
And if the body is floating in water less than 70 degrees Fahrenheit (21 degrees Celsius) for about three weeks, the tissues turn into a soapy fatty acid known as "grave wax" that halts bacterial growth. The skin, however, will still blister and turn greenish black.
After 1 month, the liquefaction process commences. During this stage the body loses the most mass. The muscles, organs and skin are liquefied, with the cadaver's bones, cartilage and hair remaining at the end of this process.
After two weeks, the body starts to bloat and change its color to red after the blood present in the body starts to decompose. Once the corpse surpasses the fourth week, you can witness liquefaction in the rest of the remains. The teeth and nails also begin to fall during this time frame.
However, on average, a body buried within a typical coffin usually starts to break down within a year, but takes up to a decade to fully decompose, leaving only the skeleton, Daniel Wescott, director of the Forensic Anthropology Center at Texas State University, told Live Science.
Black putrefaction (10-20 days after death) – exposed skin turns black, bloating collapses and fluids are released from the body. Butyric fermentation (20-50 days after death) – the remaining flesh is removed, butyric acid is formed "fermenting" the remains and the body begins to mold if in contact with the ground.
1 to 2 weeks before death, the person may feel tired and drained all the time, so much that they don't leave their bed. They could have: Different sleep-wake patterns. Little appetite and thirst.
What Does a Dead Body Look Like Beyond That? Much longer after a month, the remains of the body will be the skeleton and dark sludge of the liquified remains. If a body is left unattended for this long in a home or vehicle, the work needed to be done to repair it is extensive.
A body presents little threat to public health in the first day following the death. However, after 24 hours the body will need some level of embalming. A mortuary will be able to preserve the body for approximately a week. Regardless of the embalming, decomposition will begin after one week.
In real life, the smell of decomposition isn't an easy odor to handle that is for sure. It can often surround the property for 50 feet or more.
But one thing in common is that the legs are neatly covered either with a blanket or half-covered with the lid of a casket. Why do they cover the legs in a casket? When a person dies, the feet swell, making it difficult for the shoes to fit, which is why the legs are covered.
Thus, it appears that death in a head-down position is a death of gradual (occasionally sudden) heart failure and not a kind of cerebral death or death by suffocation ("asphyxia").
The average time between death and the funeral is two to three weeks. This gives families enough time to make all the arrangements and ensures that the body is properly prepared. It also allows for any out-of-town family members or friends to make travel arrangements, if they wish to attend.
After someone dies, it's normal to see or hear them. Some people also reporting sensing the smell or warmth of someone close to them, or just feel a very strong sense of their presence. Sometimes these feelings can be very powerful. They may be comforting but also feel disturbing.
Weeks Before Death Symptoms
Several weeks before death, your loved one may start exhibit a range of behavioral changes relating to their sleeping patterns, eating habits and sociability. They may begin to sleep more often and for longer periods.
The first organ system to “close down” is the digestive system. Digestion is a lot of work! In the last few weeks, there is really no need to process food to build new cells. That energy needs to go elsewhere.
Marbling occurs after several days as blood and proteins begin to decompose and liberate sulfur-rich compounds, giving the corpse one of its offensive odors. After about a week, the release of those nutrient-rich fluids begins to fuel an army of microbes that further liquefy the body's soft tissue.
After death, there is are no reflexes of the pupils to light and the cornea also loses its reflex. The cornea of the deceased also become cloudy after two hours of death. Besides that, the pressure in the eyes start to decrease and the eyeballs become flaccid before it they sink into the orbits of the eyes.
From three to five days after death, the body will begin to bloat from gasses produced from internal decomposition. The body could actually double in size and turn a greenish color. Extremely unpleasant and long-lasting odors called putrification begins. Blood and foam will begin to seep from the mouth.
[1] The other changes in the eyes, in the immediate post-mortem phase, include loss of intraocular pressure and the clouding of the cornea. The intraocular pressure decreases drastically after death and reaches 4 mmHg or less within 6 hours after death.
Bloating and Putrefaction (1-4 Weeks)
This transition is part of the natural process of death. These anaerobic bacteria release foul-smelling gases as they break down cells and enzymes, causing the corpse to bloat and putrefy. This stage is characterized by a strong odor and visible changes in the body's appearance.
Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind. But even that shell won't last forever. A century in, the last of your bones will have collapsed into dust.
