Answer 10

donor compounds

Question 11

particularly effective in an alkaline pH

Answer 11

glutaraldehyde

Question 12

•Crystalline solid at room temperature

•Preserves by penetrating cellular phospholipid bi layer
•Dissociates cytoplasm of the cell
•Mainly used in cavity fluid and surface applications for
bleaching

Answer 12

phenol

Question 13

•Not compatible with wetting agents or coloring agents in
fluids
•Mainly used in cavity fluids and cold sterilization formulas
•Examples are roccal and zephrin chloride

Answer 13

quats

Question 14

• Used to dilute and dissolve chemicals
• Must keep embalming chemicals in a stable state
• Water
• Methyl and Ethyl Alcohols

Answer 14

vehicles

Question 15

• Cosmetic

* Non cosmetic

Answer 15

dye

Question 16

chemicals added to the embalming solution to deal with

varying demands predicated upon the type of embalming, the environment, and the embalming fluid to be used

Answer 16

modifying agents

Question 17

substances in a solution that are capable of
neutralizing, within limits, both acids and bases and thereby
maintaining the original, or constant pH of the solution
•Balance pH in embalming fluids
•Balance pH in decomposing tissues

Answer 17

buffers

Question 18

chemicals that increase the capability of
embalmed tissue to retain moisture
•Protects formaldehyde from reacting too soon
•Brings about cellular hydration
•Make tissue flexible and rubbery

Answer 18

humectants

Question 19

chemicals that retard the tendency of blood to become more viscous through natural post mortem processes and prevent any other adverse reactions between blood and embalming chemicals

Answer 19

anti-coagulants

Question 20

Surfactants (wetting agents)
•Lowering the surface tension of embalming solution allows
for better delivery
•Lowering capillary attraction allows for the removal of blood
•Uniformity in filtering through the capillary walls

Answer 20

surfactants

Question 21

• Supplemental fluid injection before the preservative solution
• Promotes drainage
• Prepares the tissues for the arterial solution

Answer 21

pre-injection fluids

Question 22

Supplemental fluid that is mixed and injected along with the arterial solution

Answer 22

co-injection fluids

Question 23

separate fluids or ones that enhance arterial fluids by the addition of special chemicals such
as humectants
•More viscous and heavy
•Used in dehydration cases
•Used to maintain hydration levels
•Colloidal humectants draw fluid out of the tissues depending on drainage technique

Answer 23

restorative fluids

Question 24

• Helps reduce swelling
• Draws edema from tissues into venous drainage
• Can dehydrate

Answer 24

edema fluid

Question 25

make (a liquid) thinner or weaker by adding water or another solvent to it.

Answer 25

dilution

Question 26

mixture of arterial fluid with water and/or supplemental fluids

Answer 26

primary dilution

Question 27

•Phrase is deceptive as water is often a vehicle in arterial
chemicals

Answer 27

mixture of arterial solution with body fluids

Answer 28

secondary dilution

Question 29
