Module 5: Vocabulary Review Flashcards
Arterial Fluid
(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
Arterial solution
(delivery) Movent of the vascular solution from its source (embalming machine tank) through the machine apparatus, connective tubing, and arterial tube into an artery.
Cavity fluid
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.
Supplemental fluid
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.
Accessory chemical
Chemicals used in addition to vascular (arterial) and cavity embalming fluids. Hardening compounds, preservative powders, sealing agents, and compress application agents
Index
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
Donor compounds
aldehydes, alcohols, phenols, formaldehyde
Glutaraldehyde
a disinfectant, medication, preservative, and fixative. As a disinfectant, it is used to sterilize surgical instruments
Phenol
(carbolic acid) Antiseptic/Disinfectant employed to dry moist tissues and to bleach discolored tissues.
Quats
are potent disinfectant chemicals
Vehicles
Liquid that serves as a solvent for the numerous ingredients incorporated into embalming fluids.
Dye
(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.
Modifying agents
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.
Buffers
Embalming chemical that effects the stabilization of acid base balance within embalming solutions and in embalmed tissues
Humectants
Chemical that increases the ability of embalmed tissues to retain moisture
Anti-coagulants
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
Surfactants
(surface tension reducer/wetting/penetrating/surface active agent) Chemical that reduces the molecular cohesion of liquid so that is can flow through smaller apertures
Pre-injection fluids
Fluid injected to prepare the vascular system and body tissues for the injection of the preservative vascular solution. Injected before the preservative vascular solution
Co-injection fluid
Supplement fluid used primarily to enhance the action of vascular arterial solutions
Restorative fluids
(Humectant) Supplemental fluid used with the regular arterial solution whose purpose is to retain body moisture and retard dehydration
Edema fluid
swelling caused by excess fluid trapped in your body’s tissues.
Dilution
decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to a solution.
Primary dilution
Dilution attained as the embalming solution is mixed in the embalming machine
Waterless embalming
Arterial injection of an embalming solution composed of arterial fluid, humectant, and co injection fluid. No water is added.
Secondary dilution
Dilution of the embalming fluid by the fluids in the body bot vascular and interstitial
Osmosis
Passage of solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a semipermeable membrane
Hypotonic
solution has a lower concentration of solutes than another solution.
Hypertonic
a higher osmotic pressure than a particular fluid
Isotonic
a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid.
Special Purpose Fluid
Fluids used for special purposes such as jaundice
Formalin
37% with H2O or H2O and methyl alcohol. 40% vol. of formaldehyde
Paraformaldehyde
Solid form of formaldehyde
