chapter 11

Question 1

the area on a two dimensional plane from which the droplets originate.

Answer 1

Area of convergence:

Question 2

the three dimensional space from which the blood projected

Answer 2

Area of origin:

Question 3

what do bloodstain patterns tell us?

Answer 3

• The direction from which blood originated
• The angle at which a blood droplet struck the surface
• The location or position of a victim at the time a blood wound was inflicted
• The movement of a bleeding individual at the crime scene

Question 4

Contact deposit:

Answer 4

pattern that result from being in direct contact with a blood pool or soure

Question 5

Low velocity blood spatter pattern

Answer 5

This is any pattern where gravity is the only force on the blood

Question 6

Low velocity blood spatter pattern

Answer 6

This is any pattern where gravity is the only force on the blood

Question 7

Medium- velocity blood spatter pattern

Answer 7

Caused by moderate force from an object. Causes pooled blood to scatter in a direction

Question 8

High- velocity blood spatter pattern

Answer 8

Only a result of extreme force acting on a blood source, for a high impact source
Ex: gunshot, explosion, vehicle

Question 9

ellipse

Answer 9

Blood that hits the surface at an angle

Question 10

Wipe and swipe:

Answer 10

an object contacts or transfer wet blood and smears it on a surface

Question 11

Arterial spurt:

Answer 11

blood is literally pumped of a severed artery directly onto a surface

Question 12

Cast-off:

Answer 12

when a bloody object is sung through space and throws off droplets onto a nearby surface

Question 13

Running patterns:

Answer 13

when hits a vertical surface but the volume is sufficiently high that gravity causes the droplet to run

Question 14

Secondary spatter:

Answer 14

when blood drops fall into a pre existing pool of blood

Question 15

Void pattern:

Answer 15

an object on the surface gets covered in blood, and then removed, leaving an outline of the object in a pool of blood

Question 16

drip pattern is considered what?

Answer 16

Drip pattern=secondary spatter

Question 17

Expedition patterns:

Answer 17

a pattern created by blood that is expelled from the mouth or nose from internal injury

Question 18

Flows:

Answer 18

patterns made by drops or large amounts of blood flowing by the pull of gravity

Question 19

Pools:

Answer 19

when blood collects in a level and undisturbed place
