1. List the 4 divisions of vascular embalming
(1) Delivery of the arterial solution into the artery - from the embalming machine through the connecting tubing and arterial tube; (2) Distribution of arterial solution - the movement of arterial solution from the point of injection throughout the arterial system and into the capillaries; (3) Diffusion of arterial solution - movement of arterial solution from inside the vascular system (intervascular) through the walls of the capillaries into the tissue spaces (extervascular); (4) Drainage - the discharge or withdrawal of blood and blood clots, embalming solution, interstitial and lymphatic fluids and blood from the body during vascular embalming
2. The general term which describes the passage of some components of the injected embalming solution from an intravascular to an extravascular location; or the movement of the embalming solutions from the capillaries into the interstitial fluids

11. Briefly list 5 embalming procedures to follow for intravascular problems
Start with slow rate of flow to prevent coagula from floating free and clogging branches ~Inject from right common carotid when coagula are anticipated (to push coagula away from head and arms) ~Avoid sclerotic arteries (iliac and femoral) ~Use largest artery (common carotid, external iliac, femoral) ~Use proper size arterial tube
12. What is the result of resistance, as discussed by the author
Little or no resistance: tissue dehydration, reduced filtration, uneven distribution ~Total or great resistance: tissue distension, uneven distribution ~Movable resistance: blood removal is more complete, distribution is more uniform, more embalming solution is retained by the body with minimum tissue distension

Because, aspiration takes the pressure off the vascular system and thus decreases the chances of leakage from the incision should some small vessels leak
24. List some advantages of aspirating shortly after arterial injection
Large numbers of microbes are quickly removed; translocation of microbes is less likely; risk of gas and purge from microbes is minimized or prevented; removes materials that could purge; eliminates bacterial medium from hollow viscera; removal of blood helps prevent blood discolorations (most importantly); decreases swelling where neck or facial tissues have distended during arterial injection

Delay of aspiration maintains the pressure within the vascular system and allows a more thorough distribution of the arterial solution into the tissues

29. Why is clear tubing helpful in the aspiration procedure
It permits visual examination of the material being removed and aids in determining which organ or space is being aspirated
30. As a general rule, the text suggests keeping the trocar in constant motion. What is the exception
When an area is filled with liquid (such as bodies with ascites, hydrothorax, or ruptured vessels such as the aorta), the trocar should sit until the area is thoroughly drained
31. According to the lesson, aspiration also creates more "surface area" within the thorax and abdomen. What is the significance of this
It increases the amount of tissue upon which the cavity fluid can act.

The cribriform plate of the ethmoid bone
33. Describe how a gravity injector is used
The gravity injector is attached directly to the 16-ounce bottle of cavity fluid. A hose connects the injector to the trocar. The higher the bottle is raised, the faster the fluid flows into the body. A small opening on the side of the gravity injector allows air to flow into the cavity fluid bottle. By placing a finger over the opening, the embalmer stops the flow of cavity fluid. This can be done when the trocar must be withdrawn to change its position within a body cavity.

Allow time for products to work, and surfaces to dry. 2) If skin has been removed from posterior portions, elevate the body off the table using body bridges. After cleaning and disinfection, allow to air dry (fan/hair dryer may be used) to seal affected areas and preserve tissues (may take several hours). When dry, tissues will feel firm, with dark brown or yellow-brown appearance.
