What is the purpose of using an embalming machine?

The purpose of using an embalming machine is primarily to inject embalming fluid into the body. This process is a critical part of embalming, which involves preserving the deceased's tissues to delay decomposition and maintain a lifelike appearance for viewing. The embalming machine allows for a controlled and efficient introduction of the embalming fluid into the vascular system, ensuring proper distribution throughout the body.

This controlled administration is vital as it helps in effectively reducing the body's moisture content and in preserving the soft tissues, which is necessary for a successful embalming process. Using an embalming machine also allows for pressure regulation and flow control, contributing to a more uniform distribution of the preservative chemicals used during embalming.

Other options like draining blood or cleaning the body may occur during the embalming process, but these functions are not the primary purpose of the machine itself. Instead, they are part of the broader sequence of steps involved in embalming. Therefore, the correct focus regarding the embalming machine is its role in fluid injection.
