Blood Spatter Test Review

Front

What is the blood stain pattern created by the force of gravity acting alone?

Back

Passive Drop

Front

What angle is most likely for blood dropped vertically?

Back

90°

Front

How do you calculate the angle of impact of a blood droplet?

Back

Using the formula: Angle = arcsin(width/length) where width is the width of the droplet and length is the length of the droplet.

Front

What type of evidence does blood type represent?

Back

Class

Front

Which blood type contains Type A antibodies?

Back

Type B and Type O

Front

What is the definition of passive blood stains?

Back

Stains that are formed by the force of gravity, such as drops, flows, and pools.

Front

What is the difference between low velocity impact spatter and high velocity impact spatter?

Back

Low velocity impact spatter results from a force of 5 feet per second or less, while high velocity impact spatter results from a force greater than 100 feet per second.

Front

What is the significance of blood spatter analysis in forensic science?

Back

It helps to reconstruct the events of a crime scene by analyzing the patterns and distribution of blood.

Front

What is the formula to determine the angle of impact from blood droplet dimensions?

Back

Angle of impact = arcsin(diameter of droplet / length of droplet).

Front

What does a drip pattern indicate in blood spatter analysis?

Back

It indicates that blood has fallen vertically from a height, often due to gravity.
