- 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.

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.

Brain cells can die if deprived of oxygen for more than three minutes. Muscle cells live on for several hours. Bone and skin cells can stay alive for several days. It takes around 12 hours for a human body to be cool to the touch and 24 hours to cool to the core. Rigor mortis commences after three hours and lasts until 36 hours after death.
