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.
CSF absorption and drainage is essential in order to maintain the homeostasis of CSF pressure within the CNS. An imbalance between production and drainage can cause a significant rise in pressure resulting in reduced cerebral blood flow and therefore oxygen supply to the brain.
