Forensics Unit 5 Blood & Blood Spatter

Explain 'Flow Pattern' in bloodstain analysis.

• A pattern formed when blood flows in a specific direction due to gravity or movement.

• A random distribution of blood droplets on a surface.

• A pattern created by the splashing of blood from a moving object.

• A design formed by the pooling of blood in a confined area.

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

• Passive Drop

• Spatter Pattern

• Transfer Stain

• Impact Pattern

What type of blood spatter is typically created from a gunshot?

• Low Velocity

• Medium Velocity

• High Velocity

• Passive Blood Flow

What is the purpose of the Kastle-Meyer test?

• To determine the presence of blood, specifically human blood, by a color change.

• To test for the presence of alcohol in a sample.

• To identify the type of bacteria in a culture.

• To measure the pH level of a solution.

Define 'Passive Drop' in bloodstain pattern analysis.

• A bloodstain pattern created solely by the force of gravity.

• A bloodstain pattern created by a high-velocity impact.

• A bloodstain pattern resulting from a splatter effect.

• A bloodstain pattern caused by a projectile motion.

What blood spatter pattern is created when a source of blood remains stationary over a surface causing an accumulation of blood?

• Pool

• Spray

• Mist

• Drip

What is 'Medium Velocity Impact Spatter'?

• Blood spatter resulting from a force applied to blood, typically from blunt force trauma.

• Blood spatter resulting from high-speed projectiles.

• Blood spatter caused by a small amount of blood falling from a height.

• Blood spatter resulting from a slow drip of blood.

Explain the term 'Void' in bloodstain pattern analysis.

• An area devoid of blood spatter, indicating an object or person blocked the blood.

• A pattern of blood spatter that indicates the direction of the blood flow.

• A type of blood spatter that occurs when blood is projected from a moving object.

• A term used to describe the color of blood in different lighting conditions.

Define 'High Velocity Impact Spatter'.

• Blood spatter resulting from a high-energy impact, such as a gunshot.

• Blood spatter caused by a low-energy impact, such as a drop from a height.

• Blood spatter that occurs during a slow-moving object collision.

• Blood spatter resulting from natural causes, such as a sneeze.

What is a 'Drip Pattern' in bloodstain analysis?

• A pattern formed by blood dripping from a source, typically due to gravity.

• A pattern created by blood splattering upon impact.

• A pattern resulting from blood being sprayed from a moving object.

• A pattern formed by blood pooling on a surface.
