Morticians prepare bodies for cremation or burial. They are usually formally trained at a mortuary college or via an apprenticeship. When morticians gains possession of a body, they begin the ceremonial rites. They first disinfect the body with a germicide. They then drain all the blood from the blood vessels of the deceased. Morticians then fill the blood vessels with embalming fluid and dyes to preserve the condition of the body, delay any decay or infection and to help the body to look healthy for a funeral service or viewing. Morticians also position the body in the casket to help it look more presentable.
