The Dubai Police have cleared the release of Bollywood icon Sridevi's body for the embalming process, ending her family's two-day wait for bringing the body home for cremation. Embalming is the process of preserving the human body after death to delay decomposition. Human beings have been practising embalming in various forms for thousands of years. There are two main types of embalming: arterial and cavity. The arterial process works by replacing blood with embalming fluids, whereas cavity involves draining and filling the abdomen and chest.
