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 ...
Rigor mortis, the limbs of the corpse becoming stiff (Latin rigor) and difficult to move or manipulate; Putrefaction, the beginning signs of decomposition; Of these, with obvious mortal damage to the body, the textbook conclusive signs of death clear to a lay person are: algor mortis, rigor mortis, livor mortis, and putrefaction.

Some indicators that investigators use are rigor mortis, livor mortis, algor mortis, clouding of the corneas, state of decomposition, presence/absence of purged fluids and level of tissue desiccation. [2] Pathologists can assume a time of death via analysing necrophagous diptera. The odour from decaying flesh attracts different species as the ...
Rigor mortis: stiffening of limbs. Conditions at the scene of death affect the estimation of time of death. To algor mortis, livor mortis and rigor mortis, together with consideration of stomach contents, there needs to be some observation of environmental conditions at the death scene to accurately measure the PMI (Fig. 1).

Putrefaction is the fifth stage of death, following pallor mortis, livor mortis, algor mortis, and rigor mortis. This process references the breaking down of a body of an animal post-mortem . In broad terms, it can be viewed as the decomposition of proteins , and the eventual breakdown of the cohesiveness between tissues, and the liquefaction ...
A substudy of gerontology known as biogerontology seeks to eliminate death by natural aging in humans, often through the application of natural processes found in certain organisms. [10] However, as humans do not have the means to apply this to themselves, they have to use other ways to reach the maximum lifespan for a human, often through ...
