Mar 24, 2021 · A human body is almost entirely composed of four elements: oxygen, hydrogen, nitrogen and carbon. With three of those being gaseous, cremated remains contain a hefty carbon content that can be purified down to this single elemental building block of society’s most storied stone.

After death, the body breaks down into simpler organic matter through biological and chemical processes. This process can take anywhere from a few weeks to a few years, depending on a number of factors. Chemical reactions involved in the decay process will speed up as the temperature increases.
- Kidneys. These hard nuggets grow when minerals, usually calcium, build up in your urinary tract. They can really hurt, especially in your back near your hips and ribs, if they get big enough to block all or some of your pee.
- Throat. Your tonsils are two lumps of tissue at the back of your throat that help filter out germs. Food, dead skin, or other debris can get caught there and harden into stones, called “tonsilloliths.”
- Bladder. You might get them because you don’t pee fully. Or because your urine is too high in some minerals and too low in others. These stones form on their own or after a small kidney stone slips down to the bladder and gets bigger.
- Gallbladder. This small organ in your upper right belly stores a digestive juice called bile. Cholesterol and a compound called bilirubin in the bile may lead to gallstones.

When someone dies, it may be the end of their journey through this world, but this is not the case with their body. Instead, it will begin the long process of shedding its components. So, what happens when bodies decompose, and why should we learn about it?
For the majority of us, contact with the bodies of people who have passed away begins and ends with the sad occasion of a funeral.
And even then, what we usually get is either an urn with the person’s cremated remains, or a body laid out neatly in a casket, having been carefully prepared for the occasion by a funeral home.
What happens to bodies naturally, after they have had their grand encounter with death? What if they don’t get cremated or choose to become embalmed, so as to delay the process of decomposition and keep them “fit” for viewing for longer?
Under natural conditions — for example, if the body is left out in a natural environment, or placed in a shallow grave — a lifeless body begins to slowly disintegrate, until only the bones are left for future archeologists to dig up.
In this Spotlight, we describe the process of decomposition and explain why it can be useful to understand what happens to the body after death.
Although many of us may think of decomposition as synonymous with putrefaction, it is not. In fact, the decomposition of a human body is a longer process with many stages, of which putrefaction is only one part.
Decomposition is a phenomenon through which the complex organic components of a previously living organism gradually separate into ever simpler elements.
In the words of forensic scientist M. Lee Goff, it is “a continuous process, beginning at the point of death and ending when the body has been reduced to a skeleton.”
There are several signs that a body has begun its process of decomposition, Goff explains. Perhaps the three best-known ones, which are often cited in crime dramas, are livor mortis, rigor mortis, and algor mortis.
Goff also notes that different scientists split the process of decomposition into different numbers of stages, but he advises considering five distinct stages.
The first one, the fresh stage, refers to the body right after death, when few signs of decomposition are visible. Some processes that may begin at this point include greenish discoloration, livor mortis, and tache noire.
Some insects — typically flies — may also arrive at this stage, to lay the eggs from which larvae will later hatch, which will contribute to stripping the skeleton of the surrounding soft tissue.
“As revolting as they may seem, flies and their larvae — maggots — are created perfectly for the job they need to do and many experts call them ‘the unseen undertakers of the world,'” writes pathology technician Carla Valentine in her book.
The egg-laying flies that are attracted to dead bodies, she explains, “are mainly bluebottles from the Calliphora genus,” which will “lay eggs on orifices or wounds only, because the very young larvae need to eat decaying flesh but can’t break the skin to feed.”
Another type of fly, she adds, “doesn’t lay eggs but tiny maggots, which can start consuming flesh immediately. These are descriptively named Sarcophagidae or ‘flesh flies.'”
At this point, you may well be wondering, “How could learning all these details about a body’s process of decomposition after death be of any use to me?”
Well, Doughty explains that in today’s world, thinking about death and discussing any aspects related to it have become taboo.
“We can do our best to push death to the margins, keeping corpses behind stainless-steel doors and tucking the sick and dying in hospital rooms. So masterfully do we hide death, you would almost believe we are the first generation of immortals. But we are not.”

This implicit ban on death-related topics, she says, can only deepen people’s fear of death — both their own and that of others — and contribute to spreading misinformation about dead bodies as places of contamination.
Which is why, she writes, “[a] reminder of our fallibility is beneficial, and there is much to be gained by bringing back responsible exposure to decomposition.”
Understanding what happens to a body as it decomposes can help explain why professional biohazard cleanup is often necessary, especially in cases of unattended death. In this blog post, we’ll explore the five stages of decomposition and how each impacts both the body and the surrounding environment.
Too much is unknown about what dying feels like or what, if anything, happens after you die to ever feel truly ready. However, we do know a bit about the process that occurs in the days and hours leading up to a natural death, and knowing what's going on may be helpful in a loved one's last moments.
