Blood Spatter

Surface tension and what other factor help blood cells maintain shape?

• Spike centers

• Cohesion

• Satellite droplets

• Polarity

When blood falls from high places it forms?

• spikes

• coagulations

• satellite drops

• elongation

A more elongated blood drop indicates:

• the blood landed from the opposite direction

• The blood was traveling from a perpendicular direction

• The blood was traveling at a low velocity

• The blood was traveling from a blunt object
