Module 5 vocab

Question 1

Arterial (vascular) fluid

Answer 1

concentrated, preservative, embalming chemical that is diluted with water to form the arterial solution for injection into the arterial system during vascular embalming. It’s purpose is to inactivate saprophytic bacteria and render the body tissues less susceptible to decomposition.

Question 2

Arterial Solution

Answer 2

Mixture of arterial fluid and water used for the arterial injection. May include supplemental fluids.

Question 3

Cavity fluid

Answer 3

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 4

Supplemental fluid

Answer 4

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 5

accessory chemical

Answer 5

chemicals used in addition to vascular and cavity embalming fluids. Include but are not limited to hardening compounds, preservative powders, sealing agents, mold-preventative agents, and compress application agents

Question 6

special purpose fluid

Answer 6

fluids designed for use with special body conditions such as jaundice or bodies requiring a high preservative demand as seen in bodies with renal failure, extensive burns, or decomposition

Question 7

formalin

Answer 7

a clear aqueous solution of formaldehyde and methanol used especially as a preservative

Question 8

paraformaldehyde

Answer 8

a solid form of fomaldehyde

Question 9

index

Answer 9

strength of an embalming fluid, indicated by the number of grams of pure formaldehyde gas dissolved in 100mL of water. Index usually refers to a percentage; an embalming fluid with an index of 25 usually contains 25% formaldehyde gas

Question 10

Donor Compound

Answer 10

a condensation reaction between niroparafins and certain aldehydes

Question 11

Glutaraldehyde

Answer 11

an embalming and fixative agent

Question 12

Phenol (carbolic acid)

Answer 12

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

Question 13

Quats

Answer 13

used for germicidal and deoderizing

Question 14

vehicles

Answer 14

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

Question 15

Dye (coloring agent)

Answer 15

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 16

modifying agents

Answer 16

chemical components of vascular fluids that control the rate and degree of tissue firmness by the fluid utilized (eg: humectants and buffers); chemicals for which there may be greatly varying demands predicated on the type of embalming, the environment, and the embalming fluid used.

Question 17

buffers

Answer 17

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

Question 18

humectants

Answer 18

chemical that increases the ability of embalmed tissue to retain moisture

Question 19

anti-coagulants

Answer 19

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 20

surfactants

Answer 20

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

Question 21

pre-injection fluids

Answer 21

fluid injected primarily to prepare the vascular system and body tissues for the injection of the preservative vascular (arterial) solution. This solution is injected before the preservative vascular solution is injected.

Question 22

co-injection fluid

Answer 22

supplemental fluid used primarily to enhance the action of vascular (arterial) solutions.

Question 23

restorative fluids (humectants)

Answer 23

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

Question 24

edema fluid

Answer 24

the abnormal collection of fluid in tissue spaces, serous cavities, or both

Question 25

dilution

Answer 25

the process of decreasing the concentration of a solute in a solution, usually by mixing with more solvent, for instance, adding more water to the solution

Question 26

primary dilution

Answer 26

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

Question 27

waterless embalming

Answer 27

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

Question 28

secondary dilution

Answer 28

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

Question 29

osmosis

Answer 29

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 30

hypotonic

Answer 30

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

Question 31

hypertonic

Answer 31

solution having a greater concentration of dissolved solute than the solution with which it is compared.

Question 32

isotonic

Answer 32

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