What is the primary role of embalming fluids in the preservation process?

The primary role of embalming fluids in the preservation process is to delay decomposition. Embalming fluids are specifically formulated to slow down the natural decay of the body after death. They achieve this by introducing chemicals such as formaldehyde, glutaraldehyde, and phenol into the tissues, which effectively inhibit the activity of bacteria and enzymes that contribute to decay. By doing so, embalming helps to maintain the integrity of the body for a longer period, allowing for viewings, funerals, and other memorial services to occur without rapid deterioration of the remains.

While the other options mention important aspects related to embalming, such as enhancing color, changing body pH, and controlling odors, these functions are secondary to the main objective of preservation. The primary focus of embalming is to ensure that the body is presented in a dignified manner, which is facilitated through the delay of decomposition.
