What type of fluid is typically used in arterial injection during the embalming process?

In the embalming process, preservative fluid is the type of fluid most commonly used in arterial injection. This is because preservative fluid is specifically formulated to delay decomposition by inhibiting the growth of bacteria and other microorganisms. It often contains various chemicals, such as formaldehyde, methanol, and various dyes, which work together to provide both preservation and cosmetic effects for the body.

Antiseptic fluid, while it may serve a purpose in reducing infectious agents, is not primarily designed for the long-term preservation of the body, which is the main goal of arterial injection during embalming. Dehydrating fluid is used mainly to remove moisture, which is not a primary concern during early embalming. Anticoagulant fluid is typically used to prevent clotting in the blood vessels but does not serve as a primary agent for preservation purposes. Thus, preservative fluid is the best choice when discussing materials for arterial injection, ensuring that the body remains in a state suitable for viewing or burial.
