Eli5: Why dead bodies go kinda flat.

576 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.

If the body was not punctured then it would likely bloat (if recent) with gas from bacteria. If older then the corpse is eaten enough for gas to leak and making the skin loose and sunken in for a flatter look.

Because living things that stop living will decompose thanks to Maggots and all sorts of things. Try cutting one open

On second thought, no don’t try it, who knows what sicknesses you will get

Edit: Also the first step of decomposition is the autolysis, the breakdown of cells by enzymes that are already in those cells without any maggots or fungi(¿) /fungus. You could say the cells ‘eat’ themselves.

I don’t know if thats correct english, but I tried my best translating it as understandable as I could.

Probably because the dead things you usally see are squirrels, mice, rats birds etc next to roads? They are not flat because they are dead, they are dead because something made them flat.

When a person is alive and lies on a floor, they dont go flat because even laying on a floor, many muscles in their body are still working to maintain the bodies shape.

But in a dead body, the muscles undergo relaxation because, you know cause it is dead and the muscles wont have any energy to hold up the shape. That is when gravity comes into play and pulls it down, making it go flat with the floor.
