Why does a corpse turn black?

Answer 1

A corpse turns black primarily due to a process called post-mortem decomposition, where the body's tissues break down and the blood settles due to gravity, leading to livor mortis. As decomposition progresses, bacteria and enzymes break down hemoglobin in the blood, releasing pigments that can cause dark discoloration. Additionally, the reaction of tissue with various environmental factors can contribute to the darkening of the skin. This process is influenced by factors such as the environment, temperature, and time since death.
