Understanding Blood Spatter Analysis

What is the primary function of red blood cells (RBCs)?

• To fight infections

• To carry oxygen

• To produce antibodies

• To clot blood

Which blood type is known as the universal donor?

• A

• B

• AB

• O

What does the presence of the Rh factor on red blood cells indicate?

• Blood type

• Oxygen carrying capacity

• Presence of a third protein

• Clotting ability

What is the purpose of Anti-A, B, D serum in blood typing?

• To increase blood flow

• To detect specific antigens

• To enhance oxygen transport

• To prevent blood clotting

What is the term for the small drops of blood that break off from the parent spatter?

• Spines

• Satellite spatter

• Parent droplet

• Point of origin

In blood spatter pattern analysis (BSPA), what does the point of origin refer to?

• The location where the blood was first detected

• The 3D location from which spatter originated

• The surface where blood landed

• The type of blood cell involved

What are spines in the context of blood spatter?

• The main body of the blood droplet

• The pointed edges of a stain that radiate out

• The small drops that break off from the main droplet

• The area where blood is most concentrated

What is the role of serum in blood analysis?

• To carry oxygen

• To fight infections

• To contain antibodies

• To form blood clots

Which blood type is known as the universal recipient?

• A

• B

• AB

• O

What does the term "parent droplet" refer to in blood spatter analysis?

• The first drop of blood in a crime scene

• The droplet from which a satellite spatter originates

• The largest droplet in a spatter pattern

• The droplet that determines blood type
