Human Decomposition

The duration it takes for a dead body to decompose depends on various factors, any of which may affect the necessary time it takes to break the body down. If a body is exposed to the elements, the decaying process will be very fast. The most important thing to remember in decomposition is the exposure of the dead body to bacteria. In order to survive, bacteria need oxygen and are found in large concentrations in water. Therefore, if a dead body is exposed to water or air, then it will dramatically decompose. Insects and animals will feed on tissues if a dead body is exposed to them, and this also quickens the decomposing process. 

When a person’s heart stops pumping blood to the body, the cells and tissues are denied oxygen and rapidly start dying.Substantial decomposition mostly occurs in the course of two weeks, and the body’s soft tissues start disintegrating even with preservation. If the body does not get enough protection from the elements, it can even skeletonize in a space of a year. However, the teeth and bones can last even for a hundred years if the soil is not highly acidic and warm.
Five general stages are used to describe the process of decomposition in vertebrate animals: fresh, bloat, active and advanced decay, and dry/remains. The general stages of decomposition are coupled with two stages of chemical decomposition: autolysis and putrefaction. These two stages contribute to the chemical process of decomposition, which breaks down the main components of the body.
