Pigs: stages of body cooling after death. In pigs, the decrease in body temperature occurs in the eyeball, orbit soft tissue, rectum, and muscle tissue. [29] Up to 13 hours after death, eyeball cooling in pigs provides a reasonable estimate of time since death. [30] After 13 hours, muscle and rectal temperatures in pigs are better estimates of ...
Body size is an important factor that will also influence the rate of decomposition. [22] A larger body mass and more fat will decompose more rapidly. [22] This is because after death, fats will liquify, accounting for a large portion of decomposition. [22] People with a lower fat percentage will decompose more slowly. [22]
Decomposition in animals is a process that begins immediately after death and involves the destruction of soft tissue, leaving behind skeletonized remains. The chemical process of decomposition is complex and involves the breakdown of soft tissue, as the body passes through the sequential stages of decomposition. [2]
The breakdown of the proteins of a decomposing body is a spontaneous process. Protein hydrolysis is accelerated as the anaerobic bacteria of the digestive tract consume, digest, and excrete the cellular proteins of the body.

Natural embalming processes in peat bogs or salt deserts can delay the process indefinitely, sometimes resulting in natural mummification. [4] The rate of skeletonization and the present condition of a corpse or carcass can be used to determine the time of death. [5] Skeletonization occurs much quickier if vertebrate scavengers consume flesh.
A measured rectal temperature can give some indication of the time of death. Although the heat conduction which leads to body cooling follows an exponential decay curve, it can be approximated as a linear process: 2 °C during the first hour and 1 °C per hour until the body nears ambient temperature.
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 process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition.
