 FACT: When Jessica cuts the goons arm she tells him that he will  bleed 30 liters/minute. The blood flow through a brachial artery is  nowhere near that much. During vigorous exercise the entire heart  puts out a total of 30 L/min, but thats the sum total flow through  every artery of the body. The flow though a single brachial artery  is fraction of that. In addition, the goon was not vigorously  exercising. At rest, the cardiac output is about 5 L/min.
