Embalming techniques are methods used to preserve a deceased body, primarily for viewing or burial. The process typically involves the injection of a formaldehyde-based solution into the body's arteries, which helps to slow down decomposition. This solution replaces bodily fluids and helps maintain the body's appearance. In addition to arterial embalming, other techniques may include cavity embalming, where fluids are removed from the abdominal and thoracic cavities, and surface embalming, which involves applying embalming chemicals to the skin. These methods ensure that the body remains in a presentable state for memorial services and funerals, allowing loved ones to say their final goodbyes.
