What does the word embalmed mean?

Embalming is the replacement of the blood from a dead body with embalming fluid, particularly a solution of water and formaldehyde, to preserve the body. It became popular in the U.S. after the body of Abraham Lincoln toured the country after being embalmed. Also, some believe that embalming was practiced as a way to make sure a body is dead, thereby preventing the accidental burial of a living person.
