Module Five

Question 1

Accessory chemical

Answer 1

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

Question 2

Anti-coagulants

Answer 2

Ingredient of embalming fluids that retards the natural postmortem tendency of blood to become more viscous or prevents adverse reactions between blood and other embalming chemicals

Question 3

Arterial fluid

Answer 3

Concentrated, preservative, embalming chemical that is diluted with water to form the arterial solution for injection into the arterial system during vascular embalming

Question 4

Arterial solution

Answer 4

Mixture of arterial fluid and water used for the arterial injection.

Question 5

Buffers

Answer 5

Embalming chemical that effects the stabilization of acid-base balance within embalming solutions and in embalming tissues

Question 6

Cavity fluid

Answer 6

Embalming chemical that is injected into a body cavity following aspiration in cavity embalming. Cavity fluid can also be used as the chemical in hypodermic and surface embalming.

Question 7

Co-injection fluid

Answer 7

Question 8

Dilution

Answer 8

Adding in water to make another liquid weaker

Question 9

Donor compounds

Answer 9

Compounds that are combined with certain aledhydes

Question 10

Dye

Answer 10

Question 11

Edema fluid

Answer 11

Abnormal accumulation of fluids in tissues of body cavities

Question 12

Formalin

Answer 12

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

Question 13

Glutaraldehyde

Answer 13

Preservative that removes less moisture from tissues

Question 14

Humectants

Answer 14

Chemical that increases the ability of embalmed tissue to retain moisture

Question 15

Hypertonic

Answer 15

Solution having a greater concentration of dissolved solute that the solution with which it is compared

Question 16

Hypotonic

Answer 16

Solution having a lesser concentration of dissolved solute than the solution with which it is compared

Question 17

Index

Answer 17

The amount of formaldehyde gas in grams present in concentrated fluid

Question 18

Isotonic

Answer 18

A solution having a concentration of dissolved solute equal to that of a standard of reference

Question 19

Modifying agents

Answer 19

Chemical components of vascular fluids that control the rate and degree of tissue firmness by the fluid utilized

Question 20

Osmosis

Answer 20

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 21

Paraformaldehyde

Answer 21

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

Question 22

Phenol

Answer 22

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

Question 23

Pre-injection fluids

Answer 23

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

Question 24

Primary dilution

Answer 24

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

Question 25

Quats

Answer 25

Potent disinfectant

Question 26

Restorative fluids

Answer 26

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

Question 27

Secondary dilution

Answer 27

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

Special purpose fluid

Answer 28

designed to arrest and control the causative agent (clostridium perfringens) of tissue gas

Question 29

Supplemental fluid

Answer 29

A fluid the embalmer injects prior to the preservative solution or adds to the preservative solution to enhance certain qualities of the preservative fluid

Question 30

Surfactants

Answer 30

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

Question 31

Vehicles

Answer 31

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