Mortuary science is the study of deceased bodies through mortuary work. The term is most often applied to a college curriculum in the United States that prepares a student for a career as a mortician or funeral director. Many also study embalming to supplement their mortuary science studies. Some states require funeral directors to be embalmers as well. Students applying for mortuary science should have a plan about it and must develop passion for the study before applying for the course at the college level. This would make students study hard and become knowledgeable on the subject matter.
