postmortem stain
A postmortem discoloration brought about by a rupture of the red blood cells and a release of their content into the tissues is
cadaveric lividity
A postmortem intravascular blood discoloration
adipocere
A soapy waxy by-product of saponification
postmortem caloricity
A temporary rise in temperature after death is called
chemical change
Decomposition of the human body is a chemical change or a physical change?
less than seven
If a solution is acid, its pH will be
lining of the trachea and larynx
In the normal case, the first organ to decompose is the
alkaline pH
In the primary flaccidity stages of rigor mortis the pH of the muscular tissue is
lining of the trachea and larynx
In the usual case, the first organ to decompose is the
cadaveric lividity
Livor mortis is synonymous with
1. algor mortis 2. dehydration 3. hypostasis 4.livor mortis 5. increase blood viscosity
Name some postmortem physical changes
decomposition
Odor, purge,skin slip are signs of
hemolysis
Postmortem staining is due to
coagulation
The action of HCHO on protein is termed
faster
The cooling of an emaciated body would be
slower
The cooling of the body of a corpulent person would be
decay
The decomposition of aerobic bacteria is
putrefaction
The decomposition of anaerobic bacteria is
fermentation
The decomposition of carbohydrates results from
lipolysis
The decomposition of fats occurs by
putrefaction
The decomposition of of protein by the action of anaerobic bacteria is
decay
The decomposition of protein by the action of aerobic bacteria is
autolysis
The digestion of cells by means of their own enzymes is called
postmortem extravascular discoloration
The discoloration which is considered to be most permanent is
carbohydrates
The first body compounds to decompose are
carbohydrates
The first body compounds to decompose are the
yellow-green
The initial color of decomposing tissue is
hydrolysis
The method by which the body breaks down carbohydrates is called
99 degrees F
The optimum temperature to promote decomposition is approximately
algor mortis
The postmortem loss of body heat
agonal algor
The reduction of body temperature before death is called
adipocere
The saponification of fatty acids in the dead human body produces
decomposition
The separation of body compounds into simpler substances is called
desquamation (skin slip)
The seperation of the dermis and the epidermis after death is called
hemolysis
The settling of blood to the dependent parts of the body s known as
hydrolysis
The splitting apart of a compound by water is called
postmortem caloricity
The temporary rise in body temperature after death is called
formaldehyde demand
The total amount of formaldehyde required to preserve all of the protein in the body is the
amino acids
Upon hydrolysis, proteins yield
amino acids
Upon hydrolysis,proteins yield
color,odor, purge, desquamation, and gas formation
What are signs of decomposition?
putrefaction of body tissues
What are some conditions that contribute to skin slip?
atmospheric conditions
What are some extrensic factors to be considered in embalming a dead body?

Hemolysis complicates the embalming process because it
What is acid?
1.3-6.1
putrefaction and decay
According to your embalming text, proteolysis results in
pH values
Acidity or alkalanity is conveniently expressed by a scale of
body fats
Adipocere is a derivative of
hypostatic capillary conjestion
An antemortem intravascular blood discoloration
exentrensic factors
Factors influencing the rate of decomposition such as air temperature and moisture are known as
insulates
Fatty tissue in a body retards algor mortis because it
extravascular staining
Hemoglobin degradation results in
retards fluid distribution
Rigor mortis is detrimental to the embalming process because it
