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.
Embolism occurs when a collection of material such as a clot or plaque is carried through the circulatory system and becomes lodged in a vessel in such a way that it blocks blood flow. Cerebral embolism refers to blockage of a cerebral (brain) vessel by an embolus (clot or plaque). This is one form of stroke.
