What are the two grouped stages of decomposition?
Putrefaction and Autolysis
The two grouped stages of decomposition are autolysis and putrefaction.
Autolysis is the first stage of decomposition after death. It is a natural process that results from the breakdown of cells and tissues by enzymes that are present within them. During autolysis, the cells undergo a process of self-digestion, leading to the release of fluids, gases and unpleasant odors. This stage typically begins within a few hours of death and can last up to a day or two.
Putrefaction is the second stage of decomposition. It involves the breakdown of tissues and organs by bacteria and other microorganisms that are present in the environment. During putrefaction, the body undergoes significant changes in color, consistency, and odor, as the bacteria produce gases, including methane, hydrogen sulfide, and ammonia. The process of putrefaction can continue for several weeks or even months, depending on various factors, such as the temperature, humidity, and presence of scavengers or insects.
