How is blood defined when it is broken into droplets after impact?

Blood is defined as spatter blood when it is broken into droplets following an impact. This phenomenon typically occurs when a force causes blood to disperse into small droplets, resulting in a pattern that can provide vital forensic information. The presence and pattern of spatter can help investigators determine the direction and angle of the blood source and the nature of the event that caused the spatter.

In forensic science, understanding blood spatter patterns is crucial for reconstructing a crime scene or understanding the events during a violent encounter. The characteristics of spatter blood, such as droplet size and distribution, can yield insights into the dynamics of the situation that generated the spatter, such as the type of weapon used or the distance from which the blood was cast.

Other types of blood, like castoff blood, refers specifically to blood that is flung from a moving object, such as a weapon, while pooled blood refers to blood that has collected in one area without dispersion. Transfer blood occurs when a blood-covered surface comes into contact with another surface, leaving behind a print that is a direct impression of the original surface's blood.
