Embalming Quiz 2

Embalming quiz 2

QuestionAnswer
postmortem separation of the solid and liquid parts of blood plasma filtration
Signs of decomposition 1. gas formation 2. skin-slip 3. purge
blood clot containing all the elements of blood in a homogeneous mass cruror clot
proteolysis caused by aerobic bacteria decay
main by-product caused by fermentation in the dead human body carbon dioxide
white, greasy, crumbly substance caused by lipolysis under certain conditions adipocere
decomposition described as self-destruction of the cell autolysis
type of hydrolysis imbibition
optimum temperature for the growth of most bacteria responsible for decomposition 99.5 F
postmortem change that's classified as a PHYSICAL change algormortis
adipocere "grave wax". soft whitish crumbly or greasy material that forms by the postmortem hydrolysis in the presence of lipase enzyme
Algor mortis Cooling of the body to the temperature of the surrounding environment. 1 of 6 postmortem physical changes
autolysis cell self-decomposition. as the chemocal change of shift in pH from alkaline to acidic membrane of lysosomes in cell rupture and spew digestive enzymes
blood clot containing all the elements of blood in a homogeneous mass cruror clot
Change in body pH change in body tissues from alkaline to acidic during rigor to alkaline in decomposition
color change of decomposition greenish discoloration n right lower quad of abdomen
crepitation movement of gases in the tissues by pressure
decay protein decomposition caused by aerobic
decomposition described as self-destruction of the cell autolysis
decomposition order proteins -> amino acids -> amines -> ammonia proteins -> amino acids -> carbon dioxide and water ->
Decomposition separation compounds into simpler substances by the action of the bacteria and enzymes. Protein chains break down
Dehydration Loss of moisture from the surface of the body to the surrounding atmosphere via surface evaporation or gravitational hypostatis. 1 of 6 postmortem physical changes
desquamation skin slip. outer layer of skin weaken and causes the superficial skin to be pulled away more easily
Endogenous invasion of microorganisms Relocation of microorganisms in the body as a result of the cessation of natural microorganisms and metabolic activities which
fermentation bacterial decomposition Final break down is carbon dioxide and water.
imbibition ability of cells to draw moisture from surrounding area into themselves. Can cause postmortem edema
Increase in blood viscosity Thickening of the blood after death caused primarily by loss of the liquid portion of the blood to the tissue spaces (dehydration). 1 of 6 postmortem physical changes
max pH Max acidity is pH of 0
normal blood pH about 7.4
optimum temperature for the growth of most bacteria responsible for decomposition 99.5 F
order of decomposition cells -> tissue -> organs Sooner: more moisture and heat
pH acidic pH less than 7
pH alkalinity pH greater than 7
Postmortem caloricity temporary rise in body temperature after death as the cells exhaust their oxygen supply
postmortem edema designated areas of hypostatis become engorged
postmortem pH after death pH drops to acid range and stays there during rigor mortis. Eventually as body further decomposes become alkaline
postmortem separation of the solid and liquid parts of blood plasma filtration
Postmortem stain dependent areas of livor mortis begin to break down via hemolysis where hematin (heme) seeps through the capillary walls and into the body tissues. Can't be removed by arterial injection and venous drainage because it's now extravascular.
primary flaccidity part of rigor mortis
proteases breakdown during decomposition is caused by catalytic enzymes
proteolysis caused by aerobic bacteria decay
purge evacuation of liquids
putrefaction protein decomposition caused by anaerobic
Rigor mortis postmortem stiffening of muscles
secondary flaccidity as rigor mortis passes naturally from an unembalmed body within 36-72 hours
Signs of decomposition 1. gases 2. skin-slip 3. purge 4. color 5. odor
type of hydrolysis imbibition

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
