six point
arterial embalming has 2 primary functions: injection of ___ solution; and drainage of blood and other fluids from the blood ___ system
preservative and vascular
there are 4 distinct processes that actually occur simultaneously during arterial embalming: injection, ___, diffusion, and drainage
distribution
instant tissue fixation is an embalming technique that uses a very ___ arterial solution injected into a specific region using short bursts under high pressure
strong
the method of drainage where injection and drainage are allowed to proceed at the same time throughout the embalming
concurrent
the ___ is suitable when the embalmer anticipates uncomplicated distribution of embalming solution and favorable blood drainage
one point
___ is the result of inadequate preservation of the deeper tissues
shell embalming
short circuiting of arterial solution can be decreased by restricting ___ to create intravascular pressure
drainage
the ___ artery is used with a restricted cervical injection
carotid
one of the advantages of multipoint injection is it increases the overall effectiveness of embalming through the use of
sectional embalming
___ regulations require the use of multiple sites for long term preservation
military
the initial drainage is the most ___; however, all drainage should be carefully controlled and ___ should be avoided
dangerous and splashing
supplements the primary injection site when arterial solution cannot reach a particular area or when the area is insufficiently preserved
multipoint
anticipating embalming challenges (ex. poor distribution of solution, incomplete blood drainage, increased probability of tissue distension, and lengthy postmortem delays) validates ___ embalming
six point
the drainage method where injection of embalming solution continues throughout the embalming and the drainage is shut off for selected short periods
intermittent
the left side of the face is injected before the right side of the face to allow the embalmer to make adjustments prior to injecting the most visible side of the face. the order of injection is based upon ___
professional judgment
effectively controls the volume of arterial solution entering the head and the face; affords the greatest control over entry of arterial solution into the head
restricted
injection from two or more site; suitable arteries are located closer to the area insufficiently embalmed
multipoint
prevents facial distension and and dehydration when large volumes of strong solution are required to meet the preservative demand in the trunk of the body
restricted
pressure developed as the flow of embalming solution is established and the elastic arterial walls expand and then contract, resulting in the filling of the capillary beds and development of pressure filtration
intravascular pressure
movement of ___ from an intravascular location is called fluid diffusion
embalming solution
capillary walls are composed of endothelium, which lines the entire vascular system and are made up of flat, single layered cells called ___. these are thin walled cells that form the semipermeable membranes through which substances in the blood must pass to reach the body cells
squamos epithelium
___ of the arterial solution from the embalming machine through the tubing and arterial tube into the artery is one of the functions of arterial embalming
delivery
pressure placed on the outside of a blood vessel; sufficient to collapse or partially collapse the lumen of the vessel
extravascular resistance
indicates the pressure of arterial solution leaving the delivery hose and entering the body; the machine is running, the rate of flow valve is open, and fluid is being delivered
actual pressure
responsible for the movement of embalming solution from within the capillaries to the tissues; energy need originates from a non living mechanism
passive transport
the measured difference between potential and actual pressure readings; an indicator of the rate of flow (speed of delivery)
differential pressure
passage of embalming solution through the capillary wall to diffuse with the interstitial fluids by application of positive intravascular pressure; embalming solution passes from an intravascular to an extravascular position
pressure filtration
speed at which fluid is injected, measured in ounces per minute
rate of flow
rounding of fingertips, lips, and toes, drying of the tissues, and mottling of the tissues are signs of arterial solution ___
diffusion
signs of arterial solution distribution are: dye evident in the tissues, ___ of superficial blood vessels, blood drainage, and clearing of intravascular blood ___
distension and discolorations
attempt should be made to relieve rigor prior to injection. this is not always possible in ___ limbs
arthritic
veins on the backside of the hands can be distended before arterial solution is injected as a result of ___ of the blood
gravitation
passage of solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a semipermeable membrane
osmosis
an embalmer can improve arterial solution distribution by relieving extreme abdominal extravascular pressures caused by abdominal edema (ascites) using a ___
trocar
amount of pressure produced by an injection device to overcome initial resistance within (intravascular) or upon (extravascular) the vascular system (arterial or venous)
injection pressure
___ of the arterial solution from the point of injection throughout the arterial system and into the capillaries is one of the functions of arterial embalming; also referred to as ___
distribution and perfusion
an embalmer can improve arterial solution distribution by injecting the arterial solution using ___
pulsation
a mechanism that moves material across the cell membrane; energy is produced by the living cell; does not function in the dead human body
active transport
indicates the pressure existing in the delivery hose only; the machine is running but the rate of flow valve is closed, the fluid is not delivered
potential pressure
___ of the arterial solution from within the vascular system through the capillary walls and into the ___ spaces is one of the functions of arterial embalming
diffusion and tissue
the large colloid molecules, because of their large surface area, tend to ___ molecules
absorb
can be caused by either narrowing or obstruction of the lumen of a vessel
intravascular resistance
