Eli5: Why dead bodies go kinda flat.

842 views

To sum it up in short words I’ve seen alot of dead things,

Sometimes after they’ve been sitting for a while they seem to become sorta flat? I’m assuming it is due to circulation not happening anymore? No idea tbh.

Thanks.

After a while, corpses lose all the gasses inside. The abdomen in particular reduces. This is later followed by distention due to the production of new gasses during decomposition.

There is an effect called hypostasis where the blood extravases, and settles with gravity at the lower extremities, but I don’t think it affects the shape too much, but it does create a very obvious colour change in a cadaver which has been lying for many hours. It’s also called post-mortem staining.
