Description
This pattern was generated by drawing blood into a large-bore syringe and projecting it at the target.
The shape of arterial patterns can vary greatly but all deal with blood leaving the body under pressure. Patterns may have a series of large spurts as a result of larger wounds or they may be snake-like if the wound is smaller or restricted.
