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.
So what happens to the body in casket after 2 months? After bloating, it enters the 3rd phase, or 'Active Decay,' where organs liquefy. The body will lose mass, slowly revealing the skeleton. If you open the casket of a non-embalmed body, it will be more decomposed than an embalmed body in a few months or years.
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 one month, the body will have progressed solidly into the advanced decay stage. At this point, there may be large amounts of fluid (liquefaction) and gas build-up causing further bloating, swelling, and discoloration throughout the corpse. The deceased's nails and teeth will likely begin to protrude.
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.
But if we were to talk about what happens to the body after embalming, well after three – four months, the yellow-green complexion would have turned to a brownish-black colour because of the blood vessels that have deteriorated to the point that the iron inside of them spills out.
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.
As the blood pools, patches appear on the skin within 30 minutes of death. About two to four hours postmortem, these patches join up, creating large dark purplish areas towards the bottom of the body and lightening the skin elsewhere. This may be less apparent on darker skin. This process is called livor mortis.
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.
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.
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.
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.
What happens after a body is buried in a coffin? Once a body is buried in a coffin, the early stages of decomposition begin and the body undergoes active decay. After a few weeks, nails and teeth will fall out, and after one month, the liquefaction process will start to take place, causing the body to lose its mass.
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.
After a body is buried and embalmed, preservation of the body may last for a few days to a week. Depending on the humidity, climate, and soil contents, however, the decomposition process may be more rapid. Even the most heavy-duty caskets do not protect against decomposition and the elements.
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.
Phase 4: Putrefaction
This refers to the destruction of soft tissues by bacterial action. It will usually occur 2-3 weeks after death. 3rd visible sign – purge of putrid bloodstained fluid from body orifices.
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.
This stage is also one of reflection. The dying person often thinks back over their life and revisits old memories.4 They might also be going over the things they regret.
The immediate aftermath of dying can be surprisingly lively. For the first few minutes of the postmortem period, brain cells may survive. The heart can keep beating without its blood supply. A healthy liver continues breaking down alcohol.
They Know They're Dying
Dying is a natural process that the body has to work at. Just as a woman in labor knows a baby is coming, a dying person may instinctively know death is near. Even if your loved one doesn't discuss their death, they most likely know it is coming.
It is generally considered inappropriate to touch the body at an open casket funeral. If you want to touch their hand as you say goodbye or perhaps put something in the casket like a note or a small trinket, you should speak to the family in advance.
Before the embalming begins, the body is washed in a disinfectant solution. Limbs are massaged to relieve the stiffening of the joints and muscles. Any necessary shaving would also take place at this time. Your loved ones eyes are closed using glue or plastic eye caps that sit on the eye and hold the eyelid in place.
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.
