Livor mortis (from Latin līvor 'bluish color, bruise' and mortis 'of death'), postmortem lividity (from Latin post mortem 'after death' and lividitas 'black and blueness'), hypostasis (from Greek ὑπό (hypo) 'under, beneath' and στάσις (stasis) 'a standing') [1] [2] or suggillation, is the second stage of death and one of the signs of ...
[14] [12] In a clearer contemporary terminology, algor mortis, livor mortis and rigor mortis are called "early postmortem" changes, in distinction from the "immediate postmortem" changes associated with the cessation of bodily functions, as indicated by vital signs. [15] With an ophthalmoscope, changes to the blood in the retina are quickly ...
Changes to a body occurring after death (post-mortem changes) include: [3] Algor mortis: body cooling; Livor mortis: settling of blood in the lowest-placed parts of the body; Rigor mortis: stiffening of limbs. Conditions at the scene of death affect the estimation of time of death.
Timeline of postmortem changes (stages of death), with putrefaction labeled near middle. The rough timeline of events during the putrefaction stage is as follows: 1–2 days: Pallor mortis, algor mortis, rigor mortis, and livor mortis are the first steps in the process of decomposition before the process of putrefaction.
A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
Timeline of postmortem changes (stages of death), with skeletonization near right side. In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water.

Livor mortis – settling of the blood in the lower (dependent) portion of the body; Algor mortis – reduction in body temperature following death. This is generally a steady decline until matching ambient temperature; Rigor mortis – limbs of the corpse become stiff (Latin rigor) and difficult to move or manipulate
