Final Flashcards
Blood carries oxygen from the lungs to
All the other tissues in the body and in turn carry waste products, Co2
White blood cells are called Leukocytes and they have a
Nucleus and are the source of DNA testing
A Serum stain is
a pale yellowish liquid that is left behind when the clotted substances are removed
Our bodies make antibodies to protect us from
foreign molecular specifics
(Type A (Blank), Type B (Blank), Type AB (Blank), Type O (Blank))
AA, AO/BB,BO/AB/OO
If the mother is Rh-blank and the father is Rh-blank
negative, positive
Kastle-Meye color test- Hemoglobin acts like a
peroxidase
(Blank) of the bloodstains/spatter, the (Blank) of the victim at the time of blows, (Blank) of blows struck, the (Blank) of deposit, (Blank) of deposition (drip, blunt force trauma and gunshot wounds), the (Blank) of travel after injury
Origin, position, number, direction, manner, direction
Point of Origin, angle of impact = arc sin W/L
The answer is True
Gunshot back splatter
Areas from entrance wound pass back towards weapon and shooter, seen only at close range of fire, seen on inside of the barrel (exterior of weapon, hand, arm, and chest of the shooter)
Stab wound is
deeper than it is long
Incised wound is
longer than it is deep
The blade
length, width, and thickness, Single or double edges, Degree of taper from tip to hilt, Serrated r squared-off back edge, The face of the hilt guard adjacent to the blade, Groves, serration or forking of the blade, The sharpness of the edge and tip of the blade
Any object with a sharp or pointed edge can cause a sharp force injury
Knives of all types, Shears of all types, Forks of all type
Screwdrivers, picks, axes, broken bottles, ceramics, golf clubs, broom sticks, medical-surgical catheters, and probes
What is a distance shot
A wound of entrance without surrounding residue
Gun Wounds Typical Entrance:
Skin Defect, Rim of abrasion, Surrounding residue, and Surrounding discoloration due to CO
Primer is typically all 3 elements
Lead, barium, antimony.
Livor Mortis
This means literally the color of death
Estimate time since death: The first step
The window of death- between- when the deceased was last seen to be alive by a reliable witness and time pronounced dead
Newton’s law of cooling states
That the rate of cooling of an object is proportional to the temp difference between the object and its surroundings provided that this difference is not too large
Clothing, Fat
the slower body loses temp
Child, Wind
faster body temp loss
High Humidity increases
evaporation of water and hastings
Immersion in water is a
good conductor
Immersion in organic
slows conduction
