I’ve always been curious on how they know how long a body has been dead for? For example, if they say “the body has been dead for 2 hours”, how come it’s not 2 days, weeks, etc..?
edit: spelling
In: Biology
Different things happen to a body depending on how long it’s been dead. Blood stops circulating and starts pooling in certain areas. Muscles get rigid. Temperature drops. Skin dries out. After a while, bacteria in the gut cause inflation of the gut, stomach content starts digesting itself, cells deprived of oxygen and nutrients die and start falling apart. Certain insects lay eggs in favorable environment. Etc etc etc; these things happen predictably and relatively consistently, depending on the environment.
