RIGHT!!
Involves the process of preservation, disinfection, and restoration of a deceased human body - CORRECT
ANSWERS embalming chemistry
Currently the most often used preservative for embalming purposes is - CORRECT ANSWERS
methanal and formaldehyde
Actions of Preservative Chemicals - CORRECT ANSWERS Inactive the chemical groups of
proteins and/or amino acids, inhibit decomp, inactivate enzymes, kill microorganisms, destroy odors and
eliminate their further production
Reactions associated with Formaldehyde - CORRECT ANSWERS Exists in water as methylene
glycol, is prevented from polymerization to para formaldehyde by the presences of methanol, preserves
amino acids with out coagulation, denatures preserves and coagulates proteins
Complete oxidation involves - CORRECT ANSWERS the removal of all hydrogen from carbon
complete reduction involves - CORRECT ANSWERS the removal of all of the oxygen from a
compound
The action of formaldehyde on proteins is - CORRECT ANSWERS reversible in the presence of
an abundance of water
the cross linking that takes place between protein molecules in embalmed tissue occurs between
__________ in adjacent molecules - CORRECT ANSWERS nitrogen atoms
, Determined by the total amount of formaldehyde which protein will combine with to be completely
preserved - CORRECT ANSWERS formaldehyde demand
Caused by sever dehydration effect of formaldehyde on tissue - CORRECT ANSWERS searing
Basic types of embalming chemicals - CORRECT ANSWERS arterial, cavity, accessory
components of embalming solutions used to inactivate the active chemical groups of proteins and
amino acids - CORRECT ANSWERS preservatives
used as preservatives in arterial fluids - CORRECT ANSWERS aldehydes, alcohols, and phenolic
compounds
Supplemental germicides often added to some arterial fluids - CORRECT ANSWERS Quaternary
ammonium compounds and gluteraldehyde
A 5-carbon dialdehyde - CORRECT ANSWERS gluteraldehyde
Modifying agents often added to arterial fluids - CORRECT ANSWERS humectants, surfactants,
buffers
Polyhydroxy alcohols are a class of compounds often added to arterial fluids to act as a - CORRECT
ANSWERS humectant
Often used as humectants - CORRECT ANSWERS glycerol, sorbitol, and ethylene
Glycerol, sorbitol, and ethylene are all - CORRECT ANSWERS polyhydroxy alcohols and used as
humectants in arterial fluids
