Which of the following tasks is part of the embalming process that an intern must perform?

The embalming process requires specific technical skills and procedures to be performed in order to prepare the body for viewing and burial. Among these tasks, raising vessels is a fundamental part of the embalming process. This involves the careful identification and opening of arteries and veins to facilitate the injection of embalming fluid and the drainage of blood. This skill typically falls within the scope of what an intern, under supervision, would be trained to perform during their practical experience in a funeral service setting.

Other options, while related to different aspects of funeral service, do not directly pertain to the embalming process. Contacting third-party suppliers is more about business operations and logistics, obtaining signatures for obituaries typically involves administrative duties, and delivering the deceased to the cemetery is part of the logistics of funeral service, not the embalming procedure itself. Thus, raising vessels is the key task tied specifically to the internal procedures performed during embalming.
