What term describes the preservation and restoration of a body using chemicals?

The term that describes the preservation and restoration of a body using chemicals is embalming. This process involves the injection of specific chemical solutions into the body's vascular system to delay decomposition and restore a more lifelike appearance. Embalming is essential in the funeral industry as it allows for the proper viewing of the deceased during memorial services and can help families have a last chance to say goodbye in a respectful manner.

Cremation, while related to the handling of bodies after death, involves the reduction of the body to ashes through burning, not preservation. Funeral directing encompasses the overall management and orchestration of funeral services and does not specifically refer to the process of preservation. Disinfection involves cleaning and sanitizing the body to kill pathogens but does not focus on preservation or restoration using chemicals.
