-plasma
What |happens |in |the |contact/collapse |stage |of |impact? |- |CORRECT |ANSWER✔✔-Blood |droplet
|his |the |object |and |collapses |from |the |bottom |up
What |happens |in |the |displacement |stage |of |impact? |- |CORRECT |ANSWER✔✔-slight |dimples |
and |spines |begin |to |form |around |the |edge |of |the |drop
What |happens |in |the |dispersion |stage |of |impact? |- |CORRECT |ANSWER✔✔-most |of |the |volume
|of |blood |is |forced |up |and |out |so |the |spines |are |extended |outward
,What |happens |in |the |retraction |stage |of |impact? |- |CORRECT |ANSWER✔✔-surface |tension |
pulls |the |drop |flat |and |the |satellites |with |enough |momentum |break |free
What |is |satellite |spatter? |- |CORRECT |ANSWER✔✔-small |droplets |of |blood |broken |from |the |
main |drop
The |size |of |a |blood |droplet |is |dependent |on |what? |- |CORRECT |ANSWER✔✔-volume |and |
velocity
What |is |low |velocity |spatter? |- |CORRECT |ANSWER✔✔--spatter |that |is |3mm |or |greater |in |
diameter
-this |type |of |spatter |is |usually |causes |blood |to |fall |under |the |influence |of |gravity
-usually |forms |from |weapon |cast-off, |a |person |remaining |still, |walking, |or |running
What |is |medium |velocity |spatter? |- |CORRECT |ANSWER✔✔--spatter |the |is |1-3mm |in |diameter
-usually |forms |from |blunt |force |trauma, |sharp |trauma, |or |cast-off
What |is |high |velocity |spatter? |- |CORRECT |ANSWER✔✔--spatter |that |is |less |than |1mm |in |
diameter |
-appears |as |a |fine |spray |or |misting
-usually |forms |from |gunshot |trauma, |power |tools, |an |object |striking |with |extreme |velocity, |or |
an |explosion
What |is |impact/forward |spatter? |- |CORRECT |ANSWER✔✔-blood |displaced |by |energetic |impact
What |is |a |cast-off |pattern? |- |CORRECT |ANSWER✔✔-when |blood |is |released |or |thrown |from |a |
blood-bearing |object |in |motion
, What |can |you |tell |from |cast-off? |- |CORRECT |ANSWER✔✔--speed
-size |of |object
-number |of |swings
What |is |a |projected |pattern? |- |CORRECT |ANSWER✔✔-when |blood |exits |the |body |under |
pressure |from |a |breached |artery
What |is |expirated |blood? |- |CORRECT |ANSWER✔✔-blood |that |is |blown |out |of |the |mouth, |
nose, |or |a |would. |It |is |often |diluted |or |contains |mucous.
What |is |the |area |of |convergence? |- |CORRECT |ANSWER✔✔-When |you |draw |a |straight |line |
through |the |back |of |blood |stains |and |where |the |lines |intersect |is |the |area |of |convergence
How |do |you |tell |the |direction |of |a |blood |stain? |- |CORRECT |ANSWER✔✔-the |tail |(pointy |part) |
tells |which |way |the |bloodstain |goes
What |is |a |void? |- |CORRECT |ANSWER✔✔-an |absence |of |blood
What |shows |that |the |crime |scene |has |not |been |disturbed? |- |CORRECT |ANSWER✔✔--bubble |
rings
-drips
-saturation
What |can |show |the |order |of |things |that |happened |at |a |crime |scene? |- |CORRECT |
ANSWER✔✔--flow
-pattern |transfer
-skeletonization
-swipes
