  2. Chemical process of decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_process_of...

    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]

  3. Stages of human death - Wikipedia

    en.wikipedia.org/wiki/Stages_of_human_death

    The stages that follow shortly after death are: Corneal opacity, "clouding" in the eyes; Pallor mortis, paleness which happens in the first 15–120 minutes after death; Livor mortis, or dependent lividity, a settling of the blood in the lower (dependent) portion of the body; Algor mortis, the reduction in body temperature following death. This ...

  4. Putrefaction - Wikipedia

    en.wikipedia.org/wiki/Putrefaction

    The rate of putrefaction is greatest in air, followed by water, soil, and earth. The exact rate of putrefaction is dependent upon many factors such as weather, exposure and location. Thus, refrigeration at a morgue or funeral home can retard the process, allowing for burial in three days or so following death without embalming. The rate ...

  5. Corpse decomposition - Wikipedia

    en.wikipedia.org/wiki/Corpse_decomposition

    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).

  6. Asphyxiant gas - Wikipedia

    en.wikipedia.org/wiki/Asphyxiant_gas

    This desire is stimulated from increasing levels of carbon dioxide. However, asphyxiant gases may displace carbon dioxide along with oxygen, preventing the victim from feeling short of breath. In addition the gases may also displace oxygen from cells, leading to loss of consciousness and death rapidly.

  7. Uncontrolled decompression - Wikipedia

    en.wikipedia.org/wiki/Uncontrolled_decompression

    Immediately after an explosive decompression, a heavy fog may fill the aircraft cabin as the air cools, raising the relative humidity and causing sudden condensation. [4] Military pilots with oxygen masks must pressure-breathe, whereby the lungs fill with air when relaxed, and effort has to be exerted to expel the air again.

  8. Physiology of decompression - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_decompression

    The sum of these partial pressures (water, oxygen, carbon dioxide and nitrogen) comes to roughly 900 mbar (675 mmHg), which is some 113 mbar (85 mmHg) less than the total pressure of the respiratory gas. This is a significant saturation deficit, and it provides a buffer against supersaturation and a driving force for dissolving bubbles. [26]

  9. Embalming chemicals - Wikipedia

    en.wikipedia.org/wiki/Embalming_chemicals

    Embalming fluid is injected into the arterial system of the deceased's abdomen and a trocar is inserted into the body cavity. The organs in the chest cavity and the abdomen are then punctured and drained of gas and fluid contents.
