Explain embalming and its history
Embalming is the process of preserving a deceased person's body. It is typically done by injecting chemicals into the body to prevent decomposition. The chemicals used in embalming are designed to kill bacteria and other microorganisms that cause decay, and to help preserve the body's tissues. The practice of embalming has a long history, dating back to ancient civilizations such as Egypt, where it was used to preserve the bodies of the pharaohs. In modern times, embalming is often done in preparation for a funeral or memorial service.
