1. Pallor mortis- (from the Latin ‘pallor’ meaning pale) seconds after death, the body grows pale due to the lack of blood flow to capillaries.
2. Algor mortis-’ (from the Latin ‘algor’ meaning ‘coldness, ‘mortis’- of ‘death’) the body immediately goes cold. At the same time, as blood is no longer circulating, it begins to settle and stagnate causing a colour change called Livor Mortis (from the Latin ‘livor’- bluish in colour).
3. Rigor Mortis- (from the Latin ‘rigere’- meaning ‘to be stiff’) about 2-6 hours after death, the body becomes stiff. This is because there is no synthesis of ATP to enable movement and lactic acid causes rigidity in the tissue.
4. Putrefaction- (from the Latin ‘puter’- meaning ‘rotting’) Although the body is very much dead, there are many organisms living inside of the body that continue to live, and lead to the putrefaction or decaying process. Bloody froth begins to trickle from the nose and mouth.
*I wont even bother posting a picture of this because it is SO disgusting…*
5.After about a week, as these organisms work their way to other organs, the body becomes discolored, first turning green, then purple, then black. If you can’t see the change, you’ll smell it soon enough, because the bacteria create an awful-smelling gas. In addition to smelling up the room, that gas will cause the body to bloat, the eyes to bulge out of their sockets and the tongue to swell and protrude. (In rare instances, this gas has created enough pressure after a few weeks to cause decomposing pregnant women to expel the fetus in a process known as coffin birth.). Skin becomes blistered and begins to slip and waste away.
6. Mummification- If the conditions are right, the body dries out instead of liquefying in a process called butyric fermentation or mummification. A body is also considered to be mummified when all of the organs are gone due to the feeding insects.
7. Skeletonisation- the body is now well on its way to being nothing but dry bones.
