What does pressure filtration refer to in the context of embalming solution?

Pressure filtration in the context of embalming solution specifically refers to the process by which the embalming fluid, under pressure, moves from intravascular spaces (the blood vessels) into extravascular spaces (the tissues surrounding the vessels). This process is critical during the embalming process, as it ensures that the solution effectively permeates the tissues to achieve proper preservation and prevent decomposition.

The concept relies on the application of pressure which forces the embalming solution through the vascular system and into the interstitial spaces. This mechanism is vital for achieving uniform distribution of the embalming fluid throughout the body, ensuring that as much tissue as possible is treated.

While other options describe important biological or embalming processes, they do not capture the specific action of pressure filtration. Thus, understanding this mechanism is essential in the context of effective embalming practices.
