Embalming & Body Preparation Flashcards

What is autolysis in the context of post-mortem changes?

Answer: Self-digestion of cells by their own enzymes

Autolysis is the process in which cells break down due to their own digestive enzymes after cellular death disrupts normal enzyme containment.

What is the purpose of adding a dye (cosmetica) to arterial embalming fluid?

Answer: To restore a natural, lifelike skin tone

Cosmetica dye is added to arterial fluid to impart a warm, lifelike skin tone that counteracts the pallor caused by formaldehyde fixation.

Which OSHA standard most directly governs embalming room safety?

Answer: Bloodborne Pathogens Standard (29 CFR 1910.1030)

OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) most directly governs embalming safety because of the exposure to blood and other potentially infectious materials.

What does a high formaldehyde index embalming fluid cause in tissue?

Answer: Firming and dehydration of tissue

High-index embalming fluid causes rapid protein cross-linking, resulting in firmer, drier tissue that can appear dehydrated if overused.

What is the role of a humectant in embalming chemicals?

Answer: To retain moisture and keep tissues pliable

Humectants attract and retain moisture in embalmed tissues, preventing the dehydration and hardening that high-index fluids can cause.

What is the significance of algor mortis in determining time of death?

Answer: It tracks the cooling of the body after death

Algor mortis refers to the cooling of the body after death at an approximate rate of 1–1.5°F per hour, which can be used to estimate time of death.
