What does "progressive tissue fixation" refer to in the context of embalming?

Progressive tissue fixation refers to a technique in embalming where the embalming fluid is gradually introduced and penetrates the tissues over time. This method emphasizes the slow and methodical permeation of tissues with embalming fluid, which enhances preservation and helps to maintain the integrity of the body's appearance after death. By allowing the fluid to distribute evenly and gradually, the cells have a better opportunity to absorb the preservative agents effectively, resulting in more thorough fixation of bodily tissues. This technique can contribute to improved preservation of both soft and hard tissues, ensuring a more natural appearance during viewings and memorial services.

In contrast, methods that focus on accelerating decomposition, freezing tissues, or using heat for preservation do not align with the principles of progressive tissue fixation, which is specifically concerned with the careful and gradual process of embalming for optimal preservation.
