The document discusses the process of embalming, which involves preserving a dead body through chemical treatment to delay decomposition. The main steps are: verifying death, washing and massaging the body, setting facial features, injecting embalming fluid via the arteries or cavities, and applying cosmetics. Embalming aims to sanitize, preserve, and present the body for viewing through temporarily halting decay. Chemicals like formaldehyde are injected into blood vessels or body cavities to disinfect and slow microbial growth.
