Module 5: Vocabulary Review

Question 1

Arterial Fluid

Answer 1

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

Question 2

Arterial solution

Answer 2

(delivery) Movent of the vascular solution from its source (embalming machine tank) through the machine apparatus, connective tubing, and arterial tube into an artery.

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 (Pre-injections 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 (arterial) and cavity embalming fluids. Hardening compounds, preservative powders, sealing agents, and compress application agents

Question 6

Index

Answer 6

Strength of an embalming fluid. Indicated by the number of grams of pure formaldehyde gas dissolved in 100 mL of water. Refers to a percentage, an embalming fluid with an index of 25 usually contains 25% formaldehyde gas

Question 7

Donor compounds

Answer 7

aldehydes, alcohols, phenols, formaldehyde

Question 8

Glutaraldehyde

Answer 8

a disinfectant, medication, preservative, and fixative. As a disinfectant, it is used to sterilize surgical instruments

Question 9

Phenol

Answer 9

(carbolic acid) Antiseptic/Disinfectant employed to dry moist tissues and to bleach discolored tissues.

Question 10

Quats

Answer 10

are potent disinfectant chemicals

Question 11

Vehicles

Answer 11

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

Question 12

Dye

Answer 12

(coloring agent) substance 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 13

Modifying agents

Answer 13

Chemical components of vascular fluids that control rate and degree of tissue firmness by the fluid utilized. Chemicals for which there may be greatly varying demands predicted on the type of embalming, the environment, and the embalming fluid used.

Question 14

Buffers

Answer 14

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

Question 15

Humectants

Answer 15

Chemical that increases the ability of embalmed tissues to retain moisture

Question 16

Anti-coagulants

Answer 16

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

Question 17

Surfactants

Answer 17

(surface tension reducer/wetting/penetrating/surface active agent) Chemical that reduces the molecular cohesion of liquid so that is can flow through smaller apertures

Question 18

Pre-injection fluids

Answer 18

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

Question 19

Co-injection fluid

Answer 19

Supplement fluid used primarily to enhance the action of vascular arterial solutions

Question 20

Restorative fluids

Answer 20

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

Question 21

Edema fluid

Answer 21

swelling caused by excess fluid trapped in your body’s tissues.

Question 22

Dilution

Answer 22

decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to a solution.

Question 23

Primary dilution

Answer 23

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

Question 24

Waterless embalming

Answer 24

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

Question 25

Secondary dilution

Answer 25

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

Question 26

Osmosis

Answer 26

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 27

Hypotonic

Answer 27

solution has a lower concentration of solutes than another solution.

Question 28

Hypertonic

Answer 28

a higher osmotic pressure than a particular fluid

Question 29

Isotonic

Answer 29

a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid.

Question 30

Special Purpose Fluid

Answer 30

Fluids used for special purposes such as jaundice
