What happens to a dead body after 48 hours?

After 48 hours, a dead body undergoes significant decomposition due to the action of bacteria and other microorganisms. Rigor mortis, the stiffening of muscles, typically begins to dissipate, and signs of putrefaction, such as discoloration and odor, become more pronounced. The body temperature drops to match the surrounding environment, and tissues may begin to liquefy as the decomposition process accelerates. Environmental factors such as temperature, humidity, and the presence of insects can further influence the rate of decomposition.
