What innovation in preservation did Dr. William Hunter introduce?

Dr. William Hunter is credited with the innovation of arterial injection in the field of preservation for embalming. This method revolutionized the way bodies are preserved after death, allowing for the systematic injection of embalming fluids directly into the arterial system. This technique ensures that the preservative chemicals are distributed throughout the body, effectively slowing down the decomposition process and allowing for a more natural appearance during viewing.

Arterial injection specifically focuses on using the circulatory system to deliver embalming fluids to the tissues, which provides an even and effective distribution. This was a significant advancement over previous methods, as it allowed embalmers to better manage the preservation process and significantly improved the outcomes of the embalming procedure. The introduction of arterial injection marked a crucial evolution in the practice of embalming, contributing to the standards and techniques used in modern funeral service.
