Corpse decomposition

Common wild pig (boar) corpse decomposition timelapse

Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized.[1] Knowing the different stages of decomposition can help investigators in determining the post-mortem interval (PMI).[2] The rate of decomposition of human remains can vary due to environmental factors and other factors.[3] Environmental factors include temperature, burning, humidity, and the availability of oxygen.[3] Other factors include body size, clothing, and the cause of death.[3]
