- Stage 1 Fresh (1-2 days) This stage begins almost instantly from the moment of death. As the heart stops beating, the body’s cells gets deprived of oxygen and pH changes occurs.
- Stage 2 Bloated (2-6 days) This stage of decomposition includes the first visible signs of decay, namely the inflation of the abdomen due to a build-up of various gases produced by bacteria inside the body.
- Stage 3 Decay (5-11 days) The previously inflated carcass now deflates and internal gases are released. As the tissues break down the corpse will appear wet and strong odours are very noticeable.
- Stage 4 Post-Decay (10-24 days) By the time this stage is reached, decomposition slows, as most of the flesh has been stripped from the skeleton, though some may remain in denser areas such as the abdomen.
Sep 1, 2010 · Bone has two components: protein (collagen) and a mineral, hydroxyapatite. Protein degrades first, which leaves the remaining skeletal material susceptible to cracking and flaking.
Human decomposition is a natural process involving the breakdown of tissues after death. While the rate of human decomposition varies due to several factors, including weather, temperature, moisture, pH and oxygen levels, cause of death, and body position, all human bodies follow the same four stages of human decomposition.
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. However, the larvae of some blowflies and flesh flies, can easily locate and burrow down to bodies buried at 0.3 m.
Jan 2, 2023 · The moment a person dies, their body begins to break down as cells wither and bacteria invade. But how long does it take for a body to fully decompose?
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.

Many kinds of organisms live by feeding on dead bodies. Decomposition of a corpse is a continual process that can take from weeks to years, depending on the environment. Below we have divided the process into stages, which are characterised by particular physical conditions of the corpse and the presence of particular animals.
