Those embalming fluids which are intended to be injected into the cavities of the body following
aspiration - CORRECT ANSWER -Cavity fluid
List the 5 factors that affect the shelf-life of an embalming chemical. - CORRECT
ANSWER -1. Temperature extremes 2. Storage length 3. Amount of antipolymerization
agents 4. pH of the solution 5. Exposure to light

Glutaraldehyde, Alcohols - Examples: Methanol, Ethanol and Propanol, Coal Tar Derivatives -
Examples: Phenol and Cresol
Those chemicals in arterial fluid that inactivate the saprophytic bacteria and inhibit further
decomposition - CORRECT ANSWER -Preservatives
Those lipids that contain 3 fatty acids - CORRECT ANSWER -Triglycerides
Define Isomers. - CORRECT ANSWER -Two or more substances that consist of the same
molecular composition but have a different arrangement.
The common use of ethylene glycol - CORRECT ANSWER -Antifreeze
List examples of a chemical change relative to funeral services. - CORRECT ANSWER -
Embalming, Cremation, Decomposition
Those substances which are composed of 2 or more elements physically combined, though not
chemically combined - CORRECT ANSWER -Mixtures
Other than being a good humectant, how is glycerol used in the arterial injection? - CORRECT
ANSWER -It serves to facilitate the solubility and the diffusion of the formaldehyde in the
embalming operation.
