Final answer:
Gravity embalming is a method of preserving a deceased body using the natural flow of gravity. The embalming pressure achieved in gravity embalming can vary but is commonly around 1 mmHg, considering the acceleration due to gravity and temperature.
Step-by-step explanation:
Gravity embalming is a method of preserving a deceased body using the natural flow of gravity. In this process, embalming fluid is injected into the body through an artery using gravity to create the necessary pressure. The embalming pressure achieved in gravity embalming can vary depending on factors such as the height of the embalming table and the viscosity of the embalming fluid. However, a commonly used guideline is to achieve a pressure of around 1 mmHg, taking into account the acceleration due to gravity, which is 9.80665 m/s², and the temperature of 0°C.
