Blood Splatters
Passive, Transfer and Spatter
Passive stains
Drops, flows and pods, typically resulting from gravity acting on the injured body.
Transfer Stains
When and object/person with blood comes into contact with another object or surface that does not contain blood.
Spatter
High, medium, or low velocity - results from a blood drop dispersed through or due to an external force applied to a source of liquid blood. Circle = Head On, Trail - Angle
Plasma
Makes up main component of blood - consisting of waters, proteins, ions, nutrients and wastes mixed in.
Red blood cells
Carries oxygen and CO2 through body.
Platelets
Blood clotting
White blood cells
Apart of immune system.
Agglutinogens
Found on surface of blood which helps determine’s someone’s blood type depending on its absence or presence of these molecules. I.E Presence of Ani-A means blood type B.
Parts of a blood splatter
-Parent drop (big one)
-Satellites (drops surrounding parent drop)
-Spines (Spines/spikes that stick out from each blood drop)
How does height affect a blood drop?
The size of the blood drop increases with the size of the falling height.
How does surface and angled surface affect a blood drop?
Can affect size and shape of the blood drop. Hard nonporous substances produce more circular stains with smoother edges, and soft porous materials produce scalloped stains with rougher edges.
How does angle affect a blood drop?
Become more elongated or elliptical
