Which image is showing a blood drop hitting at 90 degrees?

2

Which image is showing a blood drop hitting at 10 degrees?

2

Arterial spurts or gushes typically found on walls or ceilings are caused by the pumping action of the ____________.

2

_________________ velocity—the greatest speed to which a free falling drop of blood can accelerate in air. It is dependent upon the acceleration of gravity and the friction of the air against the blood—approximately 25.1 feet/second.

2

When a blood drop is ____________ (longer than it is wide), it is possible to
determine the direction the blood was traveling when it struck a surface.

2

As moving blood strikes a surface, several forces affect the droplet of
blood. These forces are cohesion, _______________, and surface tension.

2

______________________ is an elastic characteristic along the outer edge of a liquid caused by the attraction of like molecules.

2

_______________________ tends to keep the blood moving in the direction it was traveling.

2

The location of the source of blood can be determined if there are at least __________ drops of blood spatter.
