Which of the following describes the use of a gravity injector in embalming?

The use of a gravity injector in embalming is accurately described as relying on gravity to create pressure for fluid delivery. This method is designed to allow embalming fluids to flow into the body by taking advantage of gravitational force. The elevation of the fluid reservoir above the body creates hydrostatic pressure, which facilitates the distribution of the embalming solution through the vessels and into the tissues. This process is essential for achieving effective embalming, ensuring that the fluids are adequately dispersed to preserve the body and delay decomposition.

Other methods, such as vacuum extractors or battery-powered devices, do not utilize this simple yet effective gravitational principle. Surface embalming techniques also differ in that they focus on external application rather than fluid distribution through the vascular system, highlighting the unique function of the gravity injector in the embalming process.
