The Fascinating World of Autolysis

The two processes involved in decomposition are autolysis and putrefaction. Autolysis is the initial stage of decomposition, where enzymes leak from the cells and bacteria consume the internal organs. Putrefaction is the visible stage of decomposition, which includes the bloating phase, decay phase, post decay phase, and dry stage.

The signs of the bloating phase in putrefaction include a greenish discoloration on the lower abdomen near the right hipbone, known as the marbling effect. The superficial blood vessels also appear green through the skin. The stomach starts bloating due to gas formation.

The gases responsible for the unpleasant smell of death during putrefaction are hydrogen sulphide, ammonia, carbon monoxide, and methane.
