theory UPDATED ACTUAL Exam
Questions and CORRECT Answers
Types of chemicals - Vascular (preservation)
Cavity fluids
Supplemental fluids
Special purpose
Accessory chemicals
Difference between kelco and dodge - Equal
What color and consistency is formeldahy - Color less
Gas at an ambient temperature
Formldahyde is
Highly solubale in - Water
Where is formeldahyde found , produced by , and used for - In nature
- produced by lightning
-essential to human body functions
- used to decaffeinate coffee and make button
How does foreldahyde work - Destroys putrefactive organisms when carried by a proper vehicle
and preserves tiasus by forming new chemical compound
Formaldehyde preserves tissues by - Forming new chemical compound
,What would be a proper vehicle for formaldehyde - Water
Advantages of formaldehyde - - 100% organic
- inexpensive
- bactericidal
- inhibits growth of yeasts and mold
- only small amount is needed to treat large amounts of protein
- rapid fixation
- deodorizes the body amines formed during putrefaction
Formaldehyde deodorizes the body ___ that are formed during ______ - Amines
Putrefaction
How many ounces of foreldahyde is needed to preserve the average body - 8 oz
Disivatages of formaldehyde - - rapidly coagulates blood
- converts the tissue to a gray hue when it mixes with blood not removed
- dehydrates tissue
- constricts capillary
- fixes discoloration
- Unpleasant oder
Components of arterial fluid - - preservatives
- germicides disinfectant
- vehicle
- dyes
- purfuming agents
- modify agents
, Modifying agents include - Bufferes
Anticoagulant
Humectant
Surfactant
Bufferes - Agents that serve to control the acid based balance of fluid and tissues
Humectant - Agents that help to control tissue moisture balance
Anticoagulant - Water conditioning agents
Surfactant - Setting agents , surface tension reducers, penetrating agents, surface active agents
Preserves - Chemical preservatives denature the protein in a way that prevents decompositions
enzymes from working
Fixative - Agent employed in the preparation of tissues for the purpose of maintaining the
existing form of the structure
What is the most important fixative agents - Formalin
Modifying agents - Controls the rate of action of the main preservation chemical of embalming
formulation
Why do we need modifying agents instead of just straight preservatives - When preservatives are
used alone they exert adverse effects that interferes with good embalming results
When the hardening effect of an aldehyde is delayed what happened - The more uniform
distribution of coloring or staining agents
