In the context of embalming, what is defined as the introduction of liquid into a body cavity?

The introduction of liquid into a body cavity during embalming is termed perfusion. This process involves the injection of embalming fluid through the vascular system, allowing for the distribution of preservatives and disinfectants throughout the body, thereby aiding in the preservation of the remains.

Perfusion is a critical aspect of the embalming process as it ensures that the tissues are adequately saturated and can help in reducing the decomposition process. The goal is to replace the bodily fluids with the embalming solution, which not only provides preservation but also can enhance the appearance of the deceased for viewing purposes.

Other terms present in the choices, such as infusion or application, do not accurately describe the specific process associated with the introduction of fluid into the body cavity in embalming. Drainage, while it is a necessary part of the embalming process, refers to the removal of bodily fluids, not their introduction. Therefore, perfusion stands out as the correct terminology associated with this procedure.
