A typical prokaryotic cell might contain the following parts: 1  cell wall. 2  plasma membrane. 3  cytoplasm. 4  flagella and pili.
The same is done with the jugular drain tube. A hose is attached to the drain tube, and the hose from the embalming machine is connected to the arterial tube. Drainage can also be achieved by keeping the vein open using angle forceps. Many embalmers prefer this as it allows clots and blockages to be more easily flushed from the vascular system.
Once the embalming fluid begins to flow into the arterial system, pressure begins to build up in the entire vascular system. This helps the fluid reach all parts of the body and penetrate into the tissues. Evidence of this can be seen in bulging veins throughout the body.
