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.
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.
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.
24-72 hours after death — the internal organs decompose. 3-5 days after death — the body starts to bloat and blood-containing foam leaks from the mouth and nose. 8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas.
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.
Once a body is placed in a sealed casket, the gases from decomposing cannot escape anymore. As the pressure increases, the casket becomes like an overblown balloon. However, it's not going to explode like one. But it can spill out unpleasant fluids and gasses inside the casket.
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.
Morticians will keep the body in a fridge at two degrees Celsius instead of preparing the body with chemicals. However, you need to keep in mind that a refrigerated corpse will only last for three to four weeks.
After two weeks a dead body will likely have began the bloat stage of decay, if not the active stage. If the body has not been embalmed, putrefaction may also have begun to take place resulting in skin discoloration.
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.
Changes in the muscles: Immediately after death, the muscles undergo primary relaxation, as mentioned above, which is followed by stiffening of muscles known as rigor mortis. With the onset of putrefaction, rigor mortis passes off, and secondary relaxation occurs.
Unlike caskets, coffins have six sides to them instead of four. Plus, the top of the coffin is wider than its bottom. Coffins get tapered to conform to the shape of a human form. A coffin also has a removable lid while caskets have lids with hinges.
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. A dead body looks like a dried up prune after 2 weeks in a coffin.
Opening a Casket After 5 Years
After 5 years of burial, the body's condition may be unrecognizable. Most of the tissues will have decomposed to the point where there is very little – if any – soft tissue left.
Weeks to Years: Active and Advanced Decay
The third stage of human decomposition is “active decay,” which can occur over months or years. Now in a casket, buried, and out of sight, the once-living tissues of the deceased will continue to decompose. Putrefaction will occur, and the body will discolor and blister.
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.
A body may be different in death to life because:
a mortician or funeral director has changed a body's appearance through clothing, or hair arrangement, or cosmetics. Such “dressing” of the body may be very different to how the person in life would have done it. the body smells different.
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.
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.
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.
Here is a brief summary of the changes that happen in the body in the hours and days after death: One hour: Relaxation of muscles (primary flaccidity) starts right away, followed by the skin becoming pale.
The head is commonly turned to the left in a casket to ensure the body looks more comfortable and peaceful, while also allowing mourners a better view of the deceased's face. Occasionally, the head is also turned to the left for reasons related to Christian traditionalism.
Crematoriums never reuse coffins
Some people think that crematoriums save, reuse, or resell coffins. But that would require a market for secondhand coffins, which not many people are likely to buy! It would not be hygienic to reuse coffins. After we die, our bodies can spread bacteria, which can contaminate the coffin.
Body positioning. 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.
