Quick Summary

A corpse is a dead body. The process of death involves the cessation of bodily functions, leading to changes such as pallor mortis (paleness) and cooling. Autolysis, or self-digestion by enzymes, begins decomposition, followed by rigor mortis (stiffness). Bacteria within the body then break down tissues, leading to putrefaction and further decomposition. This process is essential for nutrient cycling in ecosystems, with saprotrophic organisms like bacteria and fungi feeding on dead organic matter. Various organisms, including certain beetles, also act as scavengers, breaking down dead materials. An autopsy is a dissection and examination of a dead body to determine the cause and effects of disease.123456
