Embalming Chemicals and their use

Question 1

Chemicals used to treat the dead human body for purpose other than arterial embalming or cavity treatment - autopsy gel concentrated disinfectant powder, sealing agents

Answer 1

Accessory

Question 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.

Answer 2

Anti-coagulants

Question 3

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.

Answer 3

Arteria (vascular) Fluid

Question 4

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

Answer 4

Arterial solution

Question 5

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

Answer 5

Buffers

Question 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.

Answer 6

Cavity fluid

Question 7

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

Answer 7

Co-injection fluid

Question 8

The act of making a liquid weaker in force, content, or value.

Answer 8

Dilution

Question 9

A chemical entity that donates electrons to another compound.

Answer 9

Donor compounds

Question 10

Chemical that increases the ability of embalmed tissue to retain moisture.

Answer 10

Humectants

Question 11

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

Answer 11

Hypertonic

Question 12

An aqueous solution containing 37% formaldehyde gas by mass in water, or in water and methyl alcohol. The alcohol stabilize the formaldehyde.

Answer 12

Formalin

Question 13

Reacts through crosslinking to insolubilize both protein and polyhydroxy compounds. It makes changes the nature of protein making it unsuitable as food for bacteria and makes it resistant to decomposition changes.

Answer 13

Glutaraldehyde

Question 14

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

Answer 14

Isotonic

Question 15

Chemical components of vascular fluids that control the rate and degree of tissue firmness by the fluid utilized (e.g., 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.

Answer 15

Modifying Agents

Question 16

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

Answer 16

Osmosis

Question 17

Strength of an embalming fluid, indicated by the number of grams of pure formaldehyde gas dissolved in 100 mL of water. Index usually refers to a percentage; an embalming fluid with an index of 25 usually contains 25% formaldehyde gas. It identifies only the absolute formaldehyde gas present in any given product.

Answer 17

Index

Question 18

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

Answer 18

Phenol (Carbolic acid)

Question 19

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

Answer 19

Pre-injection fluids

Question 20

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

Answer 20

Primary dilution

Question 21

White powdery solid containing 95% formaldehyde. Can produce formaldehyde when heated. Moderate Fire risk and can react with oxidizers. Found in embalming/deodorizing powders, sealing powders, cavity desiccants, and hardening compounds.

Answer 21

Paraformaldehyde

Question 22

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

Answer 22

Restorative fluids humectant)

Question 23

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

Answer 23

Secondary dilution

Question 24

Fluids designed for use with special body conditions such as jaundice, renal failure, extensive burns, or decomposition.

Answer 24

Special purpose fluid

Question 25

A fluid the embalmer injects prior to the preservative solution (e.g., preinjection fluid) or adds to the preservative solution to enhance certain qualities of the preservative fluid (e.g., coinjection, dye, humectant, and water conditioner).

Answer 25

Supplemental fluid

Question 26

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

Answer 26

Surfactants

Question 27

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

Answer 27

Vehicles

Question 28

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

Answer 28

Waterless embalming
