Which of the following processes assists in limiting swelling during embalming?

The process that assists in limiting swelling during embalming is pressure filtration. This technique involves the application of pressure to the embalming fluid as it is injected into the body. The pressure helps to drive the fluid into the tissue spaces and can also help to push excess interstitial fluids out, which are often responsible for swelling. By promoting the movement of fluid within the tissues, pressure filtration effectively assists in reducing and controlling edema during the embalming process.

Other methods, such as glycerin application, internal tissue building, and suture incisions, serve different purposes in the embalming process. Glycerin, for example, is typically used as a humectant to assist in moisture retention and can actually promote the retention of fluids rather than limit swelling. Internal tissue building involves injecting substances to restore tissue volume or shape but does not inherently address fluid accumulation. Suture incisions may be employed to improve drainage or modify the cosmetic appearance but they do not directly affect the process of fluid handling during embalming as pressure filtration does.
