Question 1

Arterial fluid

Answer 1

Concentrated, preservative, embalming chemical that is diluted with water to form the arterial solution for injection. (IN THE BOTTLE)

Question 2

Arterial solution

Answer 2

The in-use solution composed of the concentrated fluid diluted with water and other supplemental chemicals for injection (IN THE TANK)

Question 3

Cavity fluid

Answer 3

Embalming chemical that is injected into a body cavity following aspiration in cavity embalming.

Question 4

Supplemental fluid

Answer 4

Fluid injected for purposes other than preservation and disinfection; can be injected before the arterial solution or with the arterial solution.

Question 5

Accessory chemical

Answer 5

Chemical used in addition to vascular and cavity fluids; applied to the body surface.

Question 6

Special purpose fluid

Answer 6

Fluid designed for use with special body conditions.

Question 7

Index

Answer 7

The amount of formaldehyde gas (in grams) present in 100 mL of concentrated fluid.

Question 8

Phenol (Carbolic acid)

Answer 8

Antiseptic/disinfectant employed to dry moist tissues and to bleach discolored tissues.

Question 9

Vehicle

Answer 9

Liquid that serves as a solvent for the numerous ingredients incorporated into embalming fluids.

Question 10

Dye (Coloring agent)

Answer 10

Substances that, on being dissolved, impart a definite color to the embalming solution. Dyes are classified as to their capacity to permanently impart color to the tissue of the body into which they are injected.

Question 11

Modifying agents

Answer 11

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.

Question 12

Buffers

Answer 12

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.

Question 13

Humectants

Answer 13

Chemicals that increase the capability of embalmed tissue to retain moisture.

Question 14

Anti-coagulants (water conditioning agents, water softeners)

Answer 14

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.

Question 15

Surfactants (surface tension reducer; wetting, penetrating, or surface-active agent)

Answer 15

Chemical that reduces the molecular cohesion of a liquid so that it can flow through smaller apertures.

Question 16

Pre-injection fluid

Answer 16

Fluid injected primarily to prepare the vascular system and body tissues for the injection of the preservative vascular solution.

Question 17

Co-injection fluid

Answer 17

Supplemental fluid used primarily to enhance the action of vascular solutions.

Question 18

Restorative fluid (humectant)

Answer 18

Supplemental fluid, used with the regular arterial solution, whose purpose is to retain body moisture and retard dehydration.

Question 19

Primary dilution

Answer 19

Dilution attained as the embalming solution is mixed in the embalming machine.

Question 20

Waterless embalming

Answer 20

Arterial injection of an embalming solution composed of arterial fluid, humectant, and co-injection fluid. No water is added to the solution.

Question 21

Secondary dilution

Answer 21

Dilution of the embalming fluid by the fluids in the body, both vascular and interstitial.

Question 22

Osmosis

Answer 22

Passage of solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a semipermeable membrane.

Question 23

Formalin

Answer 23

A saturated aqueous solution of formaldehyde which contains 40% by volume and 37% by weight of formaldehyde by mass in water or methyl alcohol (wood alcohol).

Question 24

Paraformaldehyde

Answer 24

Formaldehyde that drops to the bottom of the container and is not available for chemical reaction.

Question 25

Donor compounds

Answer 25

Condensation products; compounds that are combined with certain aldehydes.

Question 26

QUATS (Quaternary Ammonia Compounds)

Answer 26

Chiefly used for germicidal and deodorizing properties; mainly used in cavity fluids and cold sterilization formulas.

Question 27

Hypotonic

Answer 27

Solution containing less of a dissolved substance as the solution to which it is compared.

Question 28

Hypertonic

Answer 28

Solution containing a greater amount of dissolved substance as the solution to which it is compared.

Question 29

Gluteraldehyde

Answer 29

Disinfecting agent; capable to reacting with protein structures over a wide pH range.

Question 30

Edema fluid

Answer 30

Corrective chemical that reduces tissues swollen with edema.

Question 31

Isotonic

Answer 31

Solution containing a concentration of dissolved solute equal to that of a standard of reference.

Question 32

Dilution

Answer 32

The process of decreasing the concentration of a solute in a solution.
