The common practice of embalming has one purpose: it slows the decomposition of a dead body so that a funeral can be delayed for several days and cosmetic work can be done on the corpse. Despite the appearances it creates, it is a violent process, and the corpses still decompose.
If insects can be excluded, a body will decompose quite slowly, because maggots are the most voracious flesh feeders. Although an exposed human body in optimum conditions can be reduced to bone in 10 days, a body that is buried 1.2 m under the ground retains most of its tissue for a year.
Oftentimes, there will be at least a few days in between a person's death and their burial, and during that time, their body will begin to decompose if it's not embalmed. Embalming can stop decomposition from taking place so that families have a little bit more time to honor their loved ones.
NIH states that exposure to elevated temperatures, increased humidity, and/or water can cause accelerated decomposition. A failure to quickly or adequately refrigerate bodies may also lead to early decomposition. The location of the deceased matters greatly when it comes to the rate of decomposition.
The body takes between ten to fifteen years to decay to a point where you may just find bones, teeth and hair remaining in the casket. There may also be some excess tissue and clothing fibers that withstood the ten years of decay.
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.
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. Several weeks after death — nails and teeth fall out.
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.
Bodies decompose fastest in hot and moist environments. With higher temperatures, the bacteria in a body produce gas at a faster rate which creates more openings in the skin for flies to lay their eggs. Heat also helps break down cell structures and the liquification of bodily fluids occur in a shorter timeline.
Once the soft tissues have fully decomposed, all that remains is the skeleton. The skeleton and teeth are much more robust. Although they undergo a number of subtle changes after death, they can remain intact for many years.
Embalming of the body is only required for transportation or burial above ground in Australia. Embalming is also not necessary for cremation, which is one of the many reasons why a cremation is much more affordable than a traditional burial.
The short answer is that embalming is not required by law (in fact, the Federal Trade Commission's Funeral Law forbids any funeral home from stating the contrary)... ...
aCremation often gets asked if it is possible to view an unbembalmed body. In most cases – yes – if held soon after the death occurs. It's important to remember that decomposition begins immediately. The longer the time between death and the viewing, the greater the chance that viewing will not be recommended.
By ten-years, given enough moisture, the wet, low-oxygen environment sets off a chemical reaction that will turn the fat in the thighs and bottom to a soap-like substance called grave wax. However, in drier conditions, the body could also be mummified – that's mummification without wrappings, or chemicals.
In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water.
Stage 3: Putrefaction - 4 to 10 days after death
Bacteria break down tissues and cells, releasing fluids into body cavities. They often respire in the absence of oxygen (anaerobically) and produce various gases including hydrogen sulphide, methane, cadaverine and putrescine as by-products.
A larger body mass and more fat will decompose more rapidly. This is because after death, fats will liquify, accounting for a large portion of decomposition. People with a lower fat percentage will decompose more slowly. This includes smaller adults and especially children.
-Our body does not decompose while we are alive because blood flow keeps oxygen, carbon dioxide, nutrients, and waste products moving to where they need to go.
If the temperature is too low, or too high, fungi and bacteria cannot grow and the rate of decomposition is slow. If the leaves have a low nitrogen content, the rate of decomposition is slowed because fungi and bacteria can not extract enough nitrogen to make proteins they need for growth.
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.
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. The body's skeletal remains will be exposed, and there may be some hair and nails that have survived.
It is a common practice to cover the legs as there is swelling in the feet and shoes don't fit. As part of funeral care, the body is dressed and preserved, with the prime focus on the face. Post embalming, bodies are often placed without shoes; hence covering the legs is the way to offer a dignified funeral.
Do they remove organs when you are embalmed? One of the most common questions people have about embalming is whether or not organs are removed. The answer is no; all of the organs remain in the body during the embalming process.
If the grave site is low on water content or moisture, metal caskets are known to last even longer, over five decades. Under favorable weather conditions, experts say that metal caskets may even last more than that – up to 80 years.
