Which method of preservation involves the use of chemicals for a deceased human body?

Embalming is the method of preservation that specifically involves the use of chemicals for a deceased human body. This process entails the injection of embalming fluids, which typically contain formaldehyde, methanol, and other substances that are designed to slow down the decomposition process and enhance the appearance of the body for viewing purposes. The goal of embalming is not only to preserve the body but also to provide dignity in death and facilitate the grieving process for the bereaved family.

Cremation, on the other hand, is a process that reduces the body to ashes through intense heat, eliminating the need for chemical preservation. Disinfecting refers more to the cleaning and sanitizing of surfaces or items, which is separate from the preservation of a body. Casketing involves placing the body into a casket for burial or viewing, but does not involve the use of chemicals for preservation. Thus, embalming is uniquely identified as the preservation method utilizing chemicals specifically designed for this purpose.
