Which type of embalming fluid is most commonly used in funeral services?

The use of arterial fluid is fundamental in the embalming process within funeral services. This type of embalming fluid is specifically designed to be injected into the vascular system to preserve and disinfect the body tissues. Arterial fluid contains a mixture of formaldehyde and other chemical compounds that help to prevent decomposition, maintain tissue firmness, and enhance the appearance of the deceased. It is typically mixed with water and used during the arterial embalming process, making it a primary choice for embalmers.

In contrast, surface fluid is utilized for topical application on the skin's surface, primarily to sanitize and preserve areas of the body that require special attention but is not suitable for comprehensive embalming. Cavity fluid, while important for treating the cavities of the body post-arterial embalming, is not used as the main embalming agent. It is typically injected into the thoracic and abdominal cavities to prevent decomposition in those areas. Preservative powder is also useful for treating specific areas but serves a different purpose and is not as widely used as arterial fluid in overall body embalming procedures.

Thus, arterial fluid stands out as the most commonly used embalming fluid in funeral services, due to its essential role in the thorough preservation and presentation of the deceased.
