What is the significance of the "siphon effect" in embalming?

The siphon effect in embalming plays a crucial role in the movement of embalming fluids. When the embalming fluid is injected into the vascular system, the pressure created pushes the fluid through the arteries. The siphon effect helps facilitate this process by allowing the embalming fluid to flow with minimal resistance, maintaining a steady and efficient distribution. This principle is similar to how a liquid can be drawn from one container to another without requiring constant pressure, provided the exit point is lower than the entry point.

In practice, this means that as fluid is injected, it can also be effectively drawn back from the body due to gravity and the pressure differential, aiding in the thorough distribution of the embalming substances throughout the tissues. This efficient distribution is vital for achieving a uniform preservation of the body, which is a primary goal of the embalming process.
